Welcome to the second floor. The cloud theme continues and there's definitely no foam here - nor does it start pouring out of the walls. Instead they have a nice, soft-stepped walk to the end of the hallway where a room waits with three cups.

All of them are filled with liquid. One red, one blue and one clear like water.

It seems to proceed from here, one of the liquids must be consumed. Trying to pour it out will only result in the liquid to return.
