Water you wading for

Scratchy and Bart Simpson arrive at a pond to have a nice, refreshing swim. Scratchy jumps straight in, but Bart doesn't join him. He refuses to jump in with Scratchy, pointing to a "No Swimming" sign, despite Scratchy's constant attempts to convince him. He soon finds the sign is there for a reason.

As Scratchy attempts to get Bart into the water, he is viciously attacked by a group of piranhas. Then, he is knocked about like a beach ball by a pair of seals. With all this happening, Bart tries to help Scratchy, but his fear hinders his efforts. He tries to reach the pond with a small stick from behind a tree far away.

Scratchy tries desperately to get away from the pond, but on his way out he is covered by a crocodile's jaw and brought back in. Fighting for his life in the crocodile's mouth, it's only a matter of time before his strength fails. After the fight, Scratchy is left crawling out of the pond, missing his whole lower half.

As he crawls for safety, a blue whale emerges from the pond and lands on top of him. Slipping back into the pond, the whale reveals Scratchy only as a pool of blood and some random chunks of skin. Then, finally jumping into action, Bart throws a life preserver to Scratchy's remains, a little too late to save his poor friend.
