Since Gelatoni is only 16" tall, outfits from Build A Bear will work well on him as he's about the same size as normal BAB animals.
BAB clothes are WAY, WAY too big for Gelatoni. Pins won't even fix it. I haven't tried it, but I think his body (torso+legs) is standard UniBEAR size, while his feet are the size of the smaller UniBEAR sidekicks.
DUFFY AND BAB CLOTHES
ABSOLUTELY DO NOT FIT GELATONI…
…which is not immediately apparent looking at him in-store and
frankly is a bit of a bummer. I like that he's "unique," but I liked
the added value of sharing outfits among the characters, too.:unsure:
