Pumpkin head for Chao
Find one of the Skeleton Dogs; the easiest place is in Pumpkin Hill , combine it with your Chao. use either Knuckles or Rouge, dig around in the Chao Garden. Eventually a pumpkin will appear. give it to the Chao mixed with the Skeleton Dog it will put it on its head. If you want to take it off, either throw or hit your Chao.

Run on foot in City Escape stage (UNKNOWN WORKAGE)
At the start of the City Escape stage, instead of landing on the ground with the board, hit brake. When on foot run full speed at a wall and get knocked down. Pause the game if you fall after hitting the wall. Choose to restart the stage to run on foot and not on the board.

Big The Cat appearances
Pumpkin Hill-hiding behind the gate, waving to you.

City Escape- after the last corner in the G.U.N. truck vs. Sonic scene. Look for him at the right of the screen, running downhill 

Mission Street-where you need to knock a column over in order to use it as a step to reach a higher level, from which you hover over to a platform with a police barricade and two robots. If you miss the platform and fall in the hole, you will see Big the Cat sitting on the girders underneath the platform.
