Beaker's Empty Belly is an Explorer achievement earned by feeding the giant Tomtom's pet griffon, Beaker, some meat from the nearby meat rack.

Class, we have here an empty beaker and over here we have various size cups of water each representing my own personal troubles, problems and concerns.

He would then drink half of his milk, exchange his beaker for mine, drink all of my milk and then hand back the empty beaker. I could then go out to play having shown the empty beaker to the teacher.
