Confirming you figured it out. The point of the bin and other environment pieces is to check on the members’ abilities, in this case that sharks can bite through metal. I’ve fixed the bad ending text a little to make it less ambiguous. A large roster was the goal, the obstacle to it was I would also need different office layouts (without a fridge, and with some new puzzle taking its place) after boxing myself in with the food mechanic. Since for every food I add, I first need to learn via stream clips/vods how every other member would react to it.
Thanks for playing.
