This paper toy is a chibi Peter White (Rabbit), the one responsible for bringing Alice into Wonderland, based on the Japanese visual novel Heart no Kuni no Alice, the papercraft is created by Larry-San.
Peter is obsessed with Alice and is the prime minister at the Castle of Hearts. He was the one who brought Alice into Wonderland in the beginning. He tends to rhyme when he speaks in the English version of the manga and is a rather serious person but has a habit of acting very clingy when Alice is around.
Although he may seem too obsessed with Alice, he has known to be sly, sharp, and smart in combat, thus looked up to by Blood. He has two forms -- his human form and his rabbit form. He is almost always seen only at the Castle of Hearts as he hates "outsiders," as they bring bacteria, which he hates. This points out that he hates dirt and is quite possibly germophobic. His love for Alice is a little "Stir Crazy" for her which Alice tends to pull away from.
Peter brought Alice to Wonderland and forced her to drink a special liquid that would trap her there. It is later revealed that Peter is Alice's memories of Sunday afternoons with her sister. [Source: wikia]
