A Forest in Miniature

A Small Wilderness
Avoiding the woods
Harold does not want to get lost in a forest, so he makes a very small one with only a single tree. His solution lets him evoke wilderness while controlling its scale.
A surprising tree
The tree turns out to be an apple tree. That discovery gives the miniature landscape something to anticipate and sets up Harold's next concern: the fruit should be guarded until it ripens.
Fruit Worth Protecting

The Apples and Their Future
Anticipated pleasure
Harold thinks the apples will be tasty when they turn red. The fruit matters as a promise of later enjoyment, though it is not yet ready to eat.
Protection introduces risk
To guard the apples, Harold puts a frightening Dragon under the tree. The protective measure makes the scene more dangerous than the fruit itself, changing a pleasant expectation into a source of fear.
The Guardian Becomes a Danger

Fear Alters the Scene
A threat that works
The Dragon is terribly frightening and even frightens Harold. The creature fulfils its guarding role too effectively, making Harold back away rather than remain near the apples.
The hand slips
Harold's hand shakes while holding the crayon. The episode ends not with the fruit being eaten but with the frightened creator losing control and entering a far more perilous setting.
