Vent

"Not to be confused with the vent in Among Us."Vent is an option in Infiltrating the Airship and Completing the Mission. This result in a success in both games.

Infiltrating the Airship
During the "Pure Blooded Thief" pathway, after sneaking into the surveilance room of the Airship, Henry Stickmin can enter a vent on the left side of the room, allowing him to move deeper into the airship. Henry will be sucked through the vents, where he spots the Romanian Ruby being held in the vault.

Completing the Mission
During the "Valiant Hero" pathway, when Henry and Charles Calvin try to escape the Toppat Orbital Station but find their path blocked by a door, Charles can suggest the two of them use a vent. It works and they make their way towards the Escape Podss. As they crawl through, Charles can be heard singing a little song about crawling through vents, before a huge explosion rocks the Toppat Orbital Station.

Trivia

 * The song Charles hums while crawling in the vents is a reference to Linkin Park's song, Crawling
