Lightyear

The oxygen tanks in the movie are actually the scream canisters used in Monsters, Inc.

The hyper speed shown in the movie is extremely slow considering the distances involved. When Buzz is doing the fuel tests his speed is measured in c, with 1c being 100% hyper speed. In physics 1c is the speed of light.

The text at the start of the movie states T'Kani Prime is 4.2 million light years from Earth, which means it would take 4.2 million years to travel that distance at the speed of light. Given the Turnip is supposed to be an exploration ship, an 8 million year round trip does not seem practical.

[SPOILER] There are 3 scenes during the end credits: a mid-credits scene about two minutes into the credits that shows a bug being blasted by the laser shield, a post-credits scene immediately before the studio logos where DERIC finishes giving directions to the storehouse and realizes everyone has already left, and a final scene after the studio logos revealing that Zurg survived the explosion.
