Freedom!

"Freedom" is a sidequest of Episode 2: HOODwinked. You can access the area to start this sidequest only after the fight with Billy.

How to start the sidequest
From the school entrance go through the first door on the left you will see. On the left side of the room you'll find a cage. Talk with the Hamster in it to start the quest. You have to talk with the Hamster a second time to have it count as the first rescued pet. This quest can be started also by talking to othet pets if you want, just remember to talk with the initial pet twice to have it count.

Walkthrough
"The "Class Pet Collective", a rebel group of renegade class pets, have asked you to help them escape the school. Their preferred means of escape - getting flushed down the toilet! Make their dreams come true and flush those pets down the toilet!"

Objective: Flush 'em down!
Reach any toilet and flush the pets down. There's one in the bathroom to the right of the room where you found the last pet, one in the bathroom in the north-eastern part of East Wing or one in the bathroom in front of the school entrance. Completing the sidequest will award you 500 XP.
