Today's lesson: Some food is a little too solid

Mmmm... plastic...

As you can see here, X-Man has entered the realm of solid food. He does not yet seem to understand, however, that hard plastic is not exactly solid food. While it is solid, it is not food. The same goes for my shoulder and the plastic part of the backpack contraption. Clearly, he has misunderstood me and has now learned, and I'm sure tomorrow he won't try to ingest my entire hand or anything else that comes remotely near his mouth.
