I made this for my ephews 10th Birthday. When he comes around he sounds like this cake looks. He make a lot of noise. It was a rush to get it finished in time but I made it with 2 minutes to spare. I laid down to take a two hour nap the night before and woke up 4.5 hours later at 7am with three cakes due at noon and his due at 2pm. The cake was chocolate and vanilla. I used mmf. Sonic was a toy.
