Feeling thirsty, you bought a can of cola and walked round drinking it while looking at the animals.
When you finish the can, you look around but don't see a bin. Not wanting to waste time looking around for one you toss it under a bush.
Unfotunately one of the keepers saw you. "Hey!" he said "littering is strictly against the rules!". He blows his whistle and several other keepers come and escort you away.
You are taken to a private building. "Do you know what your punishment is?" asks the main keeper.
"Am I going to be fined?" you reply.
"No. You're going to do community service. You're going to pick up litter in the streets, and you won't stop until you've picked up a ton of trash!". he turns to one of the other keepers. "Take him to the changing room and equip him."
The keeper takes you to a strange room and tells you he'll wait outside while you change. However, you don't see any lockers or change of clothing. The only thing in the room is a strange light in the ceiling.
Suddenly you are bathed in strange green light and feel your body changing into something else - but what?
