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.
