Wonder Pets - Switching Seats
There's an episode of this show where they save two seals. Tuck and Ming-Ming argue over the front seat and decide to share it. It shows them with Tuck being overlapped by Ming-Ming, but just before they fly through the chicken thing we see that they have switched sides and Ming-Ming is being overlapped by Tuck. After they leave they are switched again.
