Belly Phase

 Belly Phase is the third stage in Octo Expansion's finale.

Gameplay
Agent 8 must navigate a series of falling platforms, jumping between them before they descend into the pool of water below.

If the player gets repeatedly splatted they have the option to skip this phase, with each splat contributing to 20% Skip Charge, where the following dialogue will be displayed:

"Blazing a trail where none seemed to exist, Agent 8 pressed on..."

Trivia

 * The Sanitized Octarians inside the moving boxes are holding old Nintendo consoles such as the Game Boy Color and Famicom.
 * It's possible for Octoballs to spawn in the moving boxes, even though they never appear in the test stations.
 * The boxes containing Sanitized Octarians have a monitor that displays what looks to be "1 + 1 =" followed by Kamabo Corporation's eye logo.
