Thanks!
No, the plushies, claw machine, etc are all 3D elements I created in Blender. I had previously made the bear for a different project, but had never rigged him or really finished him up.
The environment, claws, etc are all new. Miss Bunny, Elephant, and Penguin are brand new models while the purple bunny and blue bear were riffed off the base Teddy model.
I played your tower defense game as well!
