In this bumper, Dot looks at the bowl of bananas, then she's thinking for a banana to be a car (but it's wrong), a banana to be in the fishbowl (but it's wrong also), and finally got idea to making a banana cream pie. While Dot is making a pie, Dash walks around before he saws a banana peel and another one. Now, the scene cuts to Dot, who is finished for warming the pie in the oven, she's walking then her foot slips by a banana peel and throw her pie to the screen. Dot cleans the banana cream and lick it, then the PBS Kids logo with Dot appears in the purple background. However, this bumper was lost.
UPDATE: 16/12/17: Peeebs has already found the bumper on his YouTube channel.
