Winter

Mnemonic

A ninja creeps through the frozen night, feet crunching on ice. This is winter — the one season where even the stealthiest warrior leaves tracks behind, exposed by the white landscape stretching endlessly around him.
Additional thoughts
Picture a ninja frustrated that the ice and snow reveal every footstep — winter is the ninja's worst enemy. The two radicals (ninja on top, ice below) visually show the ninja standing on a frozen surface.
Quick recall
A ninja on ice — exposed in winter's white landscape.
