The Land Before Time XI: Invasion of the Tinysauruses. "In this installment, Littlefoot learns a lesson about telling lies, and all the Great Valley dinosaurs learn that importance and help comes in all shapes and sizes." (http://en.wikipedia.org/wiki/The_Land_Before_Time_XI:_Invasion_of_the_Tinysauruses) The orders of magnitude comment was not meant as hyperbole.

The first sequel was entirely passable for an unrelated kid's movie. The second was edging toward stupidity, but still decent based on the standards of disney stuff. I can acknowledge this.

It's only when linked to the original that they become travesties worthy of slow death.
