Trying to collect? You might end up in competition for them with this large...fish...man thing. It is a Suketoudara from PuyoPuyo the game. What's going on here?

This fish man is petting -different- Sonic dolls than the ones just above. Look at the texture of the fabric, it is fuzzy rather than smooth. The Giant Tails here must be one of the biggest Tails's around! What are the colored bits they're holding? Puyos, colored beads from a puzzle game. Each one has an expression.
