Question

Don’t go thinking your Robin Hood just cause you took an extra peppermint from the candy jar.

Answer 1

Imo

Allusion : don’t think you’re on a high pedestal like Robin Hood just because you took more than was offered. Robin Hood took from the rich and gave to the poor. The bowl holding the candy jar represents the rich, the peppermint representing the money/gold. You are the taker and the receiver.

Meaning: Don’t take more than offered and try to hold yourself at a high standard for doing such things.
