Wanna know what killed ODB? I will tell you a chilling tale...
It all started when Po brought a satanically possessed doll to Lit. Much like "the gremlins," you should not let evil harlequin dolls drink or they will hypnotize you into doing their evil bidding. (Very much like "the gremlins.")
Here is the doll and its possessed minion #1 right before she scalped herself, made a wig out of her own scalp and then put it back on and danced a scary dance to that "goodbye horses" song from Silence of the Lambs that everyone thinks is so creepy. Possessed minion #2 right before her eyes turned red and she "got all stabby."
Luckily we escaped the doll's evil clutches in Glen's rescue van.
We survived the long journey to freedom on rationed turnips and rain water.
The survivors rejoiced at having escaped certain death.
But wait! Before the credits start to roll, our hero sees something in the distance...
Oh no! The island is swarming with zombies! We're all going to die anyway!

(Betcha didn't see that coming)

The end.
