Why bother getting a bed when you can have a room-sized soft batto to cuddle up with instead? 🦇🛏️

Probably don't have a choice, since any bed you *did* have is probably dust under them by now... :3

#Fattytober 2024 - Day 15 - Park
🦇🐇

Taking a load off at the local park, Blue tries to calculate the "weight" of the situation...

Though Snow seems far more concerned with how painfully tight their belly is getting from all that serum gurgling away!

Gonna need to release that pressure real soon!

An extremely fat bunny and bat are sitting in a small moonlit park, the bunny immobilized by their fat body and the bat laying causally on their front.

The bat is reading the label on a vial of weight gain serum, trying to calculate just how massive their bunny friend will soon become, while the bunny is looking uncomfortable as their belly bloats to a massive size, getting tight and red.

A hiker is walking past, looking in shock at the bunny, seeing them as a bomb ready to explode.

#Fattytober 2024 - Day 14 - Weird
🦇🐇

Some offscreen shenanigans later, and the duo are finally free from the train! The staff even provided a dolly for Snow, though it may not be rated for the task to come..

A strange sensation in their belly, looks like it's time for the serum to work it's magic!

An extremely fat bunny with an absurdly bloated belly carried by a dolly cart is walking along, hiccuping uncontrollably as the 2 litres of weight gain serum starts to kick in, snapping their shorts.
A huge extremely busty bear bat follows behind, curious at what is happening to their friend.

#Fattytober 2024 - Day 13 - Looking
🦇🐇

When the passengers at the station arrived for their evening train, they certainly weren't expecting nearly 10 Tonnes of Bat boobs to block their entry!

This is gonna upset a few timetables...!

A massive bear bat is stuck in the doorframe of a train carrage, their massive backside catching on the doorframe.

A series of passangers are crowding around the bat's massive breasts spilling out onto the platform, some giving expressions of shock, others annoyance.

A small red panda dressed as a station master is angrily blowing their whistle at the bat, and a small tired bunny can be seen behind the bat's butt, dizzy from trying to push them out.

Thank youu :3

This is probably my favorite piece from this sequence overall, was a lot of fun drawing a bunch of different NPC chars for it ^^

With their destination reached and the serum ticking down in their bellies, the duo depart the train... only to find the entryway quite a bit more snug than before!

Gonna take quite some force to get that titanic backside through, especially for poor Snow!

Yea, I get that ^^
Always fun when you draw a big chonky dude and suddenly it's "Oops booba!" :3

Chonk Roo Birb 🔞 @buckybirbroo.bsky.social · 4d

I feel like after a certain size it doesn't really matter anymore, they look fantastically shaped to me either way :3

(I'm probably not the best judge tho, since basically all my chars end up with breasts regardless of gender x3)

#Fattytober 2024 - Day 11 - Lost Control
🦇🐇

The duo take turns drinking a drop of the mystery serum... at least they planned to!

With a sudden unexpected stop of the train, looks like Snow has managed to accidently chug the entire bottle!

Oh well, surely they'll be just fine...?

A huge bear-bat and bunny are on a train, taking a sip of a serum labelled "Gro-Max Fast Acting Weight Gain Serum".

Three comic panels at the top of the image depict the bat taking a single drop of a glowing serum from the flask, followed by the train they are on screeching to a halt, followed by the bunny with the flask in their mouth being rocked by the sudden stop and chugging the entire bottle.

Lower image depicts the bunny slumped on their chair, with the empty bottle in the foreground.

#Fattytober 2024 - Day 10 - Round
🦇🐇

With their destination drawing near, Blue feels this a perfect time to have a taste of a special brew they've been saving all day!

Snow seems a just *little* reluctant to take a drink from the intimidating round vial, though surely just a little wouldn't hurt?

In a small train car, a very large and busty bear bat in an ill fitting hoodie and shirt is holding up a massive vial reading "GRO-MAX Fast Acting Weight Gain Serum" and is offering it to the camera. A circle cutaway shows a very fat bunny opposite them, giving a mixture of shock, surprise and curiousity at the offer.

#Fattytober 2024 - Day 9 - Train
🦇🐇

The journey home seems quite a lot longer with a few... hundred? -thousand? extra pounds on their bodies, so the duo take a short ride on the local railway!

The passengers there have certainly been treated with quite the sight :3

On a small train carriage an extremely fat bear bat and bunny are sitting and happily chatting. A grey wolf is staring at them in surprise.

#Fattytober 2024 - Day 8 - "Cake"
🦇🐇

With Snow still in a donut daze, looks like Blue has to get them both home.

Lucky the batto has the appropriate amount of "cake" to give the overstuffed bun a real plush ride :3

A very fat busty bear beat is walking down an abstract walkway cheerily, listening to music from an MP3 player nestled between their breasts. A small bunny sleeping with a massive stuffed belly is laying on the bat's ass, which is massive and prominent, spilling out of their pants.

🦇🐇

Several hundred doughnuts later, and it seems the duo are done munching, for now...

Snow seems to have fallen into a minor food coma, good thing they've got a big batto friend on standby! :3

A very fat busty bear bat is standing over a small, very stuffed bunny who has fallen asleep from eating too many doughnuts. A few uneated donuts are standing around, and the table they were seated at has fallen over.

#Fattytober 2024 - Day 6 - Bloat
🦇🐇

A busy day needs plenty of snacking to keep the bun & bat fueled.

Good thing they know just the thing to keep those gurgling tums filled, probably need to learn a thing or two about moderation though...

A fat bear-bat and bunny are sitting at a table eating from a massive stack of doughnuts. They are noticably outgrowing their clothes.

#Fattytober 2024 - Day 5 - Activity
🦇🐇

Even those on the chonkier side can still enjoy a bit of activity, and yoga is a favorite for Blue!

Snow doesn't seem to have quite the love though, especially with such an... offset to their balance :3

A fat bear-bat and bunny are performing yoga poses while wearing garish bright workout clothes that barely fit. The bat is happy and effortless, but the bunny is struggling to hold still due to their huge belly.

#Fattytober 2024 - Day 4 - Shopping
🦇🐇

With some fitting (albeit snug!) clothes acquired, time for some shopping around town!

Can be a little tough for Snow to keep composure with such a hungry belly though...

A fat bear-bat and bunny are walking, holding bags of groceries. They are both wearing new hoodies and shorts, which are pretty tight against their fat bellies and hips. The bunny is struggling to carry their shopping, with a stray apple falling out of a bag they are carrying. The bat is standing cheerily, gesturing the bunny to move forward.

Well that's a new sight! Old clothes being just a bit *too big* for the pair!

Looks like they might have to grab some new attire until they can "grow" back into these :3

A chubby bear-bat and bunny are trying on old clothes, but they are way too big due to their slimmed down frames. The bat is laughing while the bunny looks embarrassed.

Fattytober 2024 - Day 1 - Something New
🦇🐰

Certainly trying something new with the bat & bun... by not drawing them *absolutely massive* to start with!

As much as I love them comically enormous, they are admittedly pretty cute slimmed down a little :3

Now let's see how long that size lasts!

A chubby bat and bunny are standing next to each other, striking poses as if dancing.

Don't think i'd be able to do Fattytober again this year since it wiped me out a lot towards the end last time.
I'll just be reposting my old ones in case anyone missed them ^^
