It sounds silly enough, but Monster likes to make mustard (and eat it too!). In fact, everyone on the entire hill loves his mustard--well, everyone except Ram. Monster hopes that the mustard will help him become friends with Ram. Ram, on the other hand, has little interest; but with a bit of persistence and a lot of kindness from Monster, Ram learns that trying new things can create special bonds. Of course, Ram has to be reminded of just how valuable those bonds are but, in the end, sees clearly.
Join Monster and Ram on their first journey together, their most important journey of all; and maybe the most sacred journey any of us take--befriending others with a genuine heart (whether you're a fan of mustard or not).
