Everyone needs Bendies. These were probably some of the very first bendies available, waaay before Toy Island tried it. Is that immense thing in the back a bendy? How do you bend it? It looks like all his limbs are attached. Also: Is Robo whistling?
Robotnik has decent 3D detailing on his suit and arms, his gloves even have the raised studs on the edges. They've set his eyes at an odd angle which isn't entirely accurate to any show, but really the bendy is more of a caricature in this case.
With the close-ups here, you can see Sally is rather cross-eyed, but they've gotten the shape of her hair right. Sonic has unusual open hands, which makes them look rather large. Still, this is a good classic bendable set.
