Planet Gaspar

Use the rail near your ship to travel to a new area. Pay attention to three instances where you'll need to jump to another track to avoid explosive crates or gaps. The final instance requires you to use your wrench to hit mines on the track.

Arrive in a new area and meet a scientist who will give you the Jetpack in exchange for 10 Telepathopuses' brains.

The brains are encased in fluid sacs. Smash these sacs to collect the brains. You will encounter Sandsharks and crab-like creatures along the way.

Once you have collected all 10 brains, return to the scientist to receive the Jetpack.

The Jetpack uses fuel, which can be replenished at green energy refueling stations.

The scientist also has an Infobot, but requires another 20 brains.

Use your Jetpack to travel to the large creature in the background, the Telepathopus, for a mini-boss fight.

The Telepathopus has a lot of health and can attack with a roar that pushes you back and electric balls that home in on you.

Defeating the Telepathopus yields 3 brains. You need to collect a total of 20 brains for the Infobot.

Collect the remaining brains from other sources (there are 80 other brains available).

Return to the scientist with 20 brains to receive the Infobot, which reveals another planet.
