I really really really did not like Cheese Sandwich. His mane and tail bothered me the entire episode because it is BROWN. I just didn't believe in him as a party pony, even when he was being a party pony it didn't ring true to me which is weird considering the voice actor. His colouring really bugged me the whole time, okay yeah the colour of (american) cheese? I guess?
He just didn't work.
Pinkie was of course wonderful.
