Fort of Gravity (じゅうりょくのとりで / Jūryoku no Toride Lit: Fort of Gravity) is the second level of the Plains world. This is also the first fort introduced in the world.

This is the eleventh level to have a secret exit, with the normal exit leading to Chomp Chomp Panic 1 (Skies, Beach, Sun in Demo 7), while the secret exit leads to Four-Room House.

The LevelEdit


Fort of Gravity (in the circle) in the world map.

The level is really challenging because in this level, you can only jump a few meters high. However, if you press the On/Off Switch button, you will jump very high. At the end of the first room, there's a Midway Point, a door leading to the next room, and a red door. At the next room, it is very puzzling. There are various obstacles, and various times to press the On/Off Switches. Then you encounter a belt ring, which leaves you upside down which leads you to the bosses. 

Secret ExitEdit

Do everything in the normal exit until you reach the room where the 2 boss doors are located. Leave the switch Off when you're upside down, so you can't battle Dumb Drum. Instead, you will battle the Pumpkin Bombs, which will trigger the secret exit if you defeat them.

Dumb DrumEdit

Dumb Drum is a boss in this level. He releases 2 enemies now and then. To defeat him, just avoid his attacks, eventually he'll get angry and fly off.

Pumpkin BombsEdit

The Pumpkin Bombs, also known as Grenade Bombs are the other bosses in this level. If you defeat them, you'll access the secret exit. To defeat them, you must destroy both of them at the same time. If you destroy only one, and let the other one fly by, the former will respawn. Remember, each Grenade Bomb has 3 hit points.
