Mouse Click: Click the snakes at specific times to release the Guinea pigs -
Then wait for the guinea pigs to blow a bubble and splatter on the animals.
* Sometimes you will be required to click other leavers as well.

As the swinging snakes regurgitate the cute little guinea pigs you must click the snakes, which will release the pigs. As gravity finds there resting place they will blow a bubble of gum that will pop and splatter on the unsuspecting victims, although by the 54th level they may no longer be called unsuspecting.
