Shuffle

Appearance
Has a clubfoot (which was not corrected during his stay in the House); uses crutches (or one crutch; can also crawl). When we first see him through Grasshopper's eyes, he is "a scrawny little boy... with a ragged haircut," blue eyes and braces.

Before the House
We do not know if he had a family, or why he was brought to the House at about 11 years of age (the last year before the seniors' graduation).

In The House
His first nick he acquired for his ability to do some magic tricks. He can also sing and play musical instruments (at least the guitar). It is not clear what happened between the "past" and the "present" that made him abandon singing (when he is sober), but it seems that Vulture was somehow involved.

On the Other Side
We know he is a Jumper, and likely a strong one. On the night before graduation he tells of his life on the Other Side ("a small town and small gigs for money"). In the Forest he is Crookshank (Russian: Кривоног, Crooked-Leg), a creature that casts for loot in the river. On the Longest Night the river brings him a sleeping bag (the same one that Red abandoned at the Crossroads and Shuffle, returning to the dorm from the card session in Vulture's tent, found there); the "last time" before that, though, it was a dead dog (Pompey, on the previous Longest).
