Jimmy Neutron's sense of adventure takes him to the comet Twonkus 3 and back again in The Adventures of Jimmy Neutron Boy Genius: Attack of the Twonkies.

Can Jimmy return the Twonkies to the comet and save the earth? With your help, it should be a breeze.

• Make invention out of everyday items
• Save up to three games
• Jimmy's robot dog, Goddard, provides assistance

Jimmy Neutron wanted to explore Twonkus 3, a comet that comes around once every year. But as he got set to return, little furry creatures called Twonkies hid in his ship and now are multiplying all over Retroville.

Jimmy needs to create some inventions to help contain the furry nuisances. With the help of a few household items and some genius ingenuity, Jimmy devises a vacuum, shrink ray and devolver, among other inventions. Now it's up to you to help him use these inventions in this side-scrolling adventure.

Because Jimmy doesn't have any weapons, at least not in the beginning, his robot dog, Goddard, comes to the rescue. Goddard can turn into a ledge for Jimmy. He can play dead (explode near an enemy and then reassemble himself). He can also run wild and knock down creatures in his path.
