🫧 Repost of a pic from July 2024 of a wobbly monobutt Spinda! A friend reminded us that it was lost when we deleted our Twitter so it's making its stunning return today-
A monobutt Spinda struggling not to fall over backwards.

Finished sketch comm for @overlardpandora.bsky.social ! Their Glaceon OC Gio as a mighty (and quite demanding) king~ The way he's looking at you, you've got something he wants, and he intends to take it!
A low angle shot of a morbidly obese anthro Glaceon wearing a crown and holding a scepter in their left (viewer's right) hand. They're looking down at the viewer with an avaricious, borderline cruel toothy grin.

Finished sketch commission for @satsumatheblue.bsky.social !

This might be the strangest lookalike item effect I've ever seen! I wonder how many tiles her rump takes up now?

Thanks for the comm!
A monochromatic sketch of the Vulpix version of the commissioner Satsuma with a giant monobutt. She's looking back in surprise, exclaiming "V-vul?" In shock. Text: Satsu ate the Big Apple? Satsu's butt grew significantly!

Finished sketch comm for @redreaper66.bsky.social of their ant character Nico (he/him) and their sona Payton (she/her!)

Thanks for the commission!
Payton the alligator lies on her back, tummy very large and round, barely able to move. She looks somewhere between happy and uncomfortable. Nico the honeypot ant is perched on her gut, kicking his feet, smugly looking down at her. Dialogue: "Y'know, Payton," "I should treat you to buffet trips more often..." "...if it means I get a seat this comfy!"

💀bro maybe you should make sure the cute lil golden charizard idol you found in a dungeon isn't some kind of ancient incense holder bro you know you don't handle incense well you're supposed to be good at this bro

A monochromatic sketch of a Scolipede, back legs lifted up and forward by their swelling belly that towers over them. The spikes of the carapace segments of their neck have golden triangle jewelry dangling from them. A pair of gold colored glasses has been thrown upwards off their sweating face. To their right lays a saddle bag, the strap snapped. To their left is a tiny golden charizard idol with an opening in its belly, in which a flame is lit. Incense fumes are rising from its nostrils like smoke.

Sketch comm for doughieglowie.bsky.social featuring Evoi! Glowie here seems a little out of her depth- with the ability to make someone fatter by booping them, and an Eevee with a nigh infinite desire for growth, how much longer will she enable this greedy lil' voi~?

Thanks for the comm!!!!
A monochromatic of Glowie, the anthro raccoon, wearing a crop top and plaid pajama pants. She's resting on top of Evoi, an eevee, who has become massively obese to the point of being completely beached on her midsection. Glowie appears apprehensive and a little panicked, while Evoi smiles widely, mouth agape, showing several sharp fangs. Dialogue: Glowie: "G-gosh, Evoi, isn't this a bit much-" Evoi: "NO! We've only just started, evoi! So keep going! Bigger! Fatter!! MORE!!!"

A discord message from Gracie posted at 1:12 PM. It reads: "I need to be a quad Alolan Ninetales that's also a tourist attraction where you can pay to hose feed me a gallon of root beer and ice cream and there's motivation to be the one to finally burst me and every night after everyone finishes trying to pop me I spend every night perched atop or pinned under my sloshy soda and ice cream filled gut belching up storms as it all churns into more blubber to stretch and deepen my stretch marks"

Commission for @maxgrimclaw.bsky.social
of their OC Cinder, featuring Bubbline-

I guess when you own a fast food chain you end up ordering from it a lot.
A morbidly obsese and overfed reshiram is laying sideways on a red couch, the ground next to it covered in brown paper bags with a logo reading "McBorgars." In the doorway past the Reshiram's massive gut, a blue draconic woman wearing black shorts, a red shirt, and a red hat stares dumbfounded at the former's bloated middle. She's holding a delivery bag, presumably full of more burgers. Dialogue: Bubbline: "Delivery for- oh my god" Cinder: "Hey. you're the delivery girl, right? Bubbline, was it?" "You opened the door. Good, you actually read the special instructions, then." "Couldja bring those over here? Can't exactly grab them myseeeEOOUUORP-"

🫧 Emergency comm for @ssalvasssnake.bsky.social of their Umbreon form struggling with some deadweight, courtesy of an inconveniently placed Full Incense!
An extremely fat Umbreon with diamond markings on their back legs and loops on their eyes and front legs. A Full Incense sits next to their right leg, clearly the source of the weight gain.

🫧 Gift for @pikachu.pmd.social , who is the prettiest wobbliest monobutt pika-princess we've ever seen~
A monochromatic sketch of a pikachu wearing a sweater, skirt, and bandana around her neck. The tip of her tail is shaped like a star. Her bottom half is incredibly round and lacks butt cheeks. She appears to be taking a heavy, waddling step with her left leg, waving around her arm to maintain balance. Text around her body reads "Wub," "Bworb," "Bwub," and "Wob."

Thanks for the commission~!
Marcie the Nidorina (left) and Sneeve the Snivy (right) are slamming their massive, round, monobutt rear ends together. A large block letter "WHAM!" behind them, white slam VFX, and several wobble lines and onomatopoeia emphasize the impact.

Commission finished for @lusmich151.bsky.social

🫧 Following a transformation into a Milotic, I decided to help Ven get ready for beauty contests! Question my methods all you like, I get results~

Thank you for the commission!
Bubbline, in her Substitute form, feeding a copious amount of Dry Pokeblocks from a basket to Ven, transformed into a Milotic. Monologue: Bubbline: "Gosh, Ven, you really do make the prettiest Milotic! Well, I'm sure all the dry Pokeblocks I've been feeding you helped a fair deal, too." "We're gonna win the next contest for sure! If you can fit on stage by then, that is~"

🫧 Birthday gift for our friend Azimuth (8/8)!
A quadrupedal shinx being inflated through the rear end by a black ridged hose. Their belly obscures all but their back legs, tail, and a bit of their left paw and ear. A small white "speech" bubble to the top right shows their blushing face, their cheeks puffed out.
