Phineas: Already did.
Baljeet: Gelatin Pool.
Phineas: Baljeet! You remember what we did at School.
At the Swimming Pool
(Everyone is swimming in the Pool, Except Phineas, Ferb and Their Friends)
Phineas: Alright. This drop will make the pool into Dark Blue.
Baljeet: Are you sure about this?
Phineas: Of course I'm sure, how bad could it be?
(He put the Drop on the Pool and then it a Gelatin out of it)
Phineas: Oh, that one is a Gelatin Drop.
Isabella: I think we need to restore the Pool.
Principal: Phineas! Ferb! And Friends! Come to my Office, right now!
Ferb: We're in trouble, right?
End of Flashback
Baljeet: Oh yeah, Forgot about that.
Phineas: This time we will never make a Gelatin Pool again.
