Dozy in Grackleland

The main goal of Grackle is to control a little lazy caterpillar named Dozy, who is a bit of a late bloomer. Hatching later than the rest of his buds, he's got to hustle across a few trees, eating leaves and avoiding danger.
The main threats of Grackle include starvation, thorns, frogs, spiders, and of course, grackles.
