Grumpy/LOTL

Grumpy is the name of a fictional dinosaur featured in the 2009 adventure film Land of the Lost. Grumpy is a dinosaur of the Tyrannosaurus species. He is but one of several dinosaurs that exists in the Lost Land between dimensions. Explorers from the modern world by the names of Rick Marshall, Holly Cantrell and Will Stanton came to the Lost Land where they had a terrifying encounter with the dinosaur inside of an immense cavern. Running away from it, they succeeded in crossing a ravine where they believed they would be safe. At this point, Rick Marshall made a crack about the T-Rex only having a brain the size of a walnut. The angry dinosaur, whom Holly had named Grumpy, understood what Marshall had said and was greatly offended.

Grumpy caught up with the group later on in the kingdom of the Sleestaks and succeeded in gobbling up Rick Marshall in one giant gulp. Fortunately, he didn't actually chew on him, and Rick was able to pass through Grumpy's digestive system and was excreted as waste. This exceedingly intimate connection forged a bond between the two and they became close pals.
