The Case of the Missing Kohlrabi

Big is shocked one morning to discover that some of his vegetables are missing from the garden. Where have they gone? He concludes that they must have been taken by someone, but who would steal the vegetables? Small is convinced it's the gwelf, even though Big tries to tell him that gwelfs aren't real.

They decide to hide out in the garden and keep watch on the vegetable patch to discover the truth. During the watch, Small notices a vegetable being tugged back down into the ground. He rushes over and grabs the plant to save it. Big appears at this moment, but it looks to him as if it's Small who is trying to take stuff from the garden!
