Billy is a infant character who appears in the 1988 Disney/Pixar short, Tin Toy.
Even though he does not appear in Toy Story 3, a few of his toys do appear at Sunnyside Daycare. This may imply that he has become a lot older and outgrown his toys (including those not seen), and donated them to Sunnyside (we never even see what he looks like when he grows up).
- In the credits of Tin Toy, Billy only plays himself.
- In Toy Story 2, when Hamm is rapidly turning the channel, Billy is briefly shown between channels.
