(@Phil) Added scene for the story

Rat gets a fishing rod and a fish to lure the cat away from the eggs. He throws the fish over the fence but the cat gets to the fish before the rat is able to control the fish using the fishing rod and the cat ends up pulling the rat towards the fence and keeps smashing him into the fence.

Sling shot
Rat puts on a helmet after hitting the fence. He uses the sling shot to launch him over the fence but he hits the fence again but nothing happens to him. Feeling quite proud of himself because the helmet protected him he takes his helmet off and smiles but at that moment the a piece of fence where the rat hit breaks and hits him on the head knocking him unconscious.
