As for stuffed animals.. You could TRY using 3D models for a pattern [this has been up for debate], but it's a tricky business. I'm not gonna get into it.
You'd be better off looking online for Digimon models.. Where I downloaded a bunch, they were already being boned and animated; I forget for which game, though. I have too much going on to even work on my own 3D, sorry. :/
