Don't Tease with the Keys

 is the eleventh mission of Happiness Research Lab.

Gameplay
The only Octarians in this mission are six Tentakooks, four of which hold keys. The Tentakooks scatter as soon as the player uses the dash track to jump to the main platform, and the player must hunt them down to capture the keys and unlock the four vaults blocking the path to the goal.

Trivia

 * Even if the player clears away the cardboard boxes that they would usually crash through when jumping to the main platform, Agent 1 will still complain about them when the player lands.
