Key 2

The Key at Caterpillar Lane

The Key is in a form of a human wearing a cloak almost covering most of its body. It is first seen in Chapter 6 where its role is technically a key in opening Caterpillar Lane.

It perished during the incident where the Duke creates a ruckus in Wonderland.

Alice was able to enter Caterpillar Lane when he accomplishes his mission of attaining loyalty from the Queen thus, obtaining the key as his reward.
