The local museum has just acquired an actual saber-toothed tiger for their new exibit. The tiger, not wanting to be caged up, devises a plan of escape. He takes tusks from another exibit and some industrial-strength adhesive and glues them into Garfield's mouth. Now the museum curators are after Garfield while the saber-toothed tiger is lounging in Garfield's house! Jon and Odie notice the difference, and call the police and the zoo to help rid them of the menace, but the tiger won't come out. Can Garfield catch the prehistoric predator and get his normal life back?
