Animated movie... Writers block!

[gRaViJa]

I have an assigment at school to make a short animated movie. I already decidded about the subject: jungle, and the main character so far is a spider. However, i can't figure out a cool/funny short story. I've been trying for weeks, and i never had such a writer block before, so i'm irritated like hell =/

So, do any of you guys have an idea for a cool story that might get me back on the rails?
