Unlimited lives:
Return to training level and find the letters to spell "FLIK" to gain a bonus life. Repeat this to obtain as many lives as needed before resuming the regular game.

Hidden training level:
Begin game play in the training level and finish all of Mr. Soil's objectives. Then, bounce on all the spiders to kill them to reach a hidden level. Complete this new level to view three FMV sequences.

Bonus levels:
There are three bonus levels in the game. For the first, abdomen bounce three to five bugs without missing one in a level. In the Tunnels level, get the blue berry and kill five grasshoppers without missing one. For the third, in the Clover Forest level, line five mushrooms up in the beginning and hop from one to the other without touching the ground. Make sure you bounce once on each of them. Finish the Bug Circus, and you will get a new FMV sequence after each one.
