Rexy (Night at the Museum)

Rexy is a giant Tyrannosaurus Rex skeleton and major exhibit in the Museum of Natural History, New York. He is a major character in Night at the Museum, a minor character in Night at the Museum: Battle of the Smithsonian, a supporting character in Night at the Museum: Secret of the Tomb and one of the deuteragonists of Night at the Museum: Secret of the Lost Tablet.

Night at the Museum
Rexy first appears when Larry visits the Museum of Natural History while looking for a job. He is the first exhibit as you enter the Museum, a large reconstructed T-rex.

When the sun goes down, Rexy is the first exhibit to come to life. On Larry's first time as a night guard, Rexy was seen "drinking" from the step-activated water fountain. Rexy chases Larry around the museum in an attempt to get him throw him a bone (one of his ribs). Rexy and Trixie are both known for their dog-like behavior and joy to play fetch.

The Manual stated that the bone must be thrown twice. The second time mentions to not throw the bone in the direction of the fossil exhibit.

Battle of the Smithsonian
Rexy is briefly seen at the start of the film Night at the Museum: Battle of the Smithsonian and is known for his tug-of-war between him and Larry.

Secret of the Tomb
Rexy appears in Night at the Museum: Secret of the Tomb and he and Trixie became friends at the end.
