First, watch the episode where there is a rat in the store

Watch the part where Kenan and Kel are discussing the rat.

You should see a lady holdind a GREEN shopping basket.

The camera then shows the rat.

The camera then shows the lady again, but this time holding a RED basket.

The camera shows something else, sorry I can't remember what.

Finally, it goes back to the lady, who is just about to run out of the store, as she is scared of the rat. She is holding a GREEN basket again.
