In Chapter 4 of Deltarune, I'm playing as a pixelated character named Kris when I encounter a hallway with a locked door, a step stool, and a bright green book on a shelf. Obviously I need to move the step stool so that Kris, or another party member, can reach the book and hit the switch mechanism I think is hidden behind it. But when I go to move the stool, there's no button prompt. I cannot do anything no matter how many times I press A. So I move on.
Instead the problem resolves itself later, when Ralsei, one of Deltarune's three main characters, bends over (imagine a lil pixelated anthropomorphized goat guy on his hands and knees) and offers his body as a step stool. My third party member, a very punk and aggressive purple dinosaur named Suzie, uses Ralsei as a step and jumps up to hit the switch. In the end Ralsei and Suzie end up pancaked on the ground, but they manage to open the door.
