(The guppies are playing supermarket)

Gil: Thank you for shopping at our supermarket.

(Mr. Grouper shows up dressed as a superhero)

Mr. Grouper: Dun-dun-dun-dun. Did someone say "supermarket"? I am Super Grouper! And I have come to your supermarket to get, you know, stuff.

Gil: You don't buy superhero stuff at a supermarket, Mr. Grouper. 

Mr. Grouper: don't? 

Dan (the supermarket clerk): You both want bubble bites?

Gil and Mrs. Peekytoe: Yes please:

Dan: Uh-oh. There's only one box of bubble bites left.

Deema: Awkward!

Molly: Orange you glad they weren't watermelons?

Mr. Grouper: I am Super Grouper!
