Agreed on all the stuckage tropes - getting stuck in the food containers is definitely a great idea. Jars, or even say a decorative bottle filled with candy, with a broad neck but small opening. With the tiny being stuck in an object, they could be helplessly moved around by the human/owner, maybe putting their trapped tiny on display however they wish, occasionally feeding them to make sure they stay trapped 😉
Oh shit I LOVE the idea of a tiny with a big bloated and/or fat tummy getting stuck in something and being put on display, moved around as the human sees fit - maybe the human tells them that they'll be shown to everyone who comes to the house so that they can all see how greedy and awful the tiny is, and shame the tiny for what they did.
And of course the visitors do gawk, marvelling at how huge the tiny's belly is, laughing at the whimsy of a tiny who got so carried away with his appetite and gluttony that he got stuck in the very container he was eating from! The tiny sometimes squirms and tries to escape, stressed and frightened by how many giants are surrounding them, pointing and laughing and gawking, only to show that they're still stuck fast and stirring the guests into a new wave of laughter.
Loveee getting stuckage asks, feel free to send more here for drabbles!
