A Bug's Life  (DVD English)

A misfit ant, looking for "warriors" to save his colony from greedy grasshoppers, recruits a group of bugs that turn out to be an inept circus troupe.

Discovering their mutual misunderstanding, the circus bugs attempt to leave, but are forced back by a bird. They save Princess Dot, the Queen's daughter and Atta's sister, from the bird as they flee, gaining the ants' trust in the process. They continue the ruse of being "warriors" so the troupe can continue to enjoy the attention and hospitality of the ants. The bird encounter inspires Flik into creating an artificial bird to scare away Hopper, leader of the grasshoppers, who is deeply afraid of birds. While the bird is being built, Hopper reveals to the other grasshoppers how greatly the ants outnumber the grasshoppers and is afraid that the ants will stand up against them.
