I feel like it's a perfect crossover because there's 2 references to Henry Stickmin in Among Us, and 1 medal you can get in Completing the Mission that is just an difficult one to get, but a huge reference including all the crewmates.

"Assemble The Crew"

This one is hard to get, because you have to find all the hidden crewmates. I think you have to select the specific leading ending badges for a certain ending in CtM and find all the hidden crewmates on your way through to get the specific ending.

"NrG Drink"

This one can be found in Among Us if one of your tasks is to buy a beverage. The Gatorade-looking NrG drink can be found next to the Don Dew in the vending machine.

"Tunisian Diamond"

This is a double reference but I just put one of them on the title for it. It can be found in the trash chute (if you are assigned the empty trash chute task.) with the teleporter, which appears as a consistent fail throughout the entire Henry Stickmin series.
