Invasion of the Tinysauruses
15 April 2009 | by (Chicago, Illinois) – See all my reviews

The Land Before Time XI: Invasion of the Tinysauruses, the eleventh installment in The Land Before Time series. After seeing the last Land Before Time movie, The Great Longneck Adventure, it was a terrific movie so I was really looking forward to this sequel. Now still this was a fun movie, had a decent story and the animation was good, just it wasn't as good as I was expecting, but it's a good movie still. This story is one that I'm too familiar with from every sit com in the world, the problem with size, how many kids are either too small or too big and are so concerned with their mega or lack their of ability of growing. But it's always a moral tale that needs a good repeat for the new generation and The Land Before Time now takes it on. But still I loved the animation, the colors are getting brighter and the movement of the characters are more clean. How could you not enjoy these sequels? Littlefoot and his friends are a joy to watch on screen together and the writers added another story of the difficulty of accepting another adult into a child's life, Invasion of the Tinyauruses is a good movie.

Every year, as the warm season approaches, a certain tree in the Great Valley blooms with pink flowers. Since they are so delicious, every dinosaur in the valley wants his/her fair share of it. Littlefoot and his friends Ducky, Petrie and Spike are eagerly waiting to nibble the first treesweets. Ducky tries to take one, but Littlefoot quickly tells her to stop and reminds them all that none may take any treesweets until "Nibbling Day". Meanwhile, Cera's father is visited by an old friend , a female treehorn named Tria, it seems he used to have a crush on her. Cera doesn't take as kindly to her as her father does as she is jealous of her relationship with her father being put on hold because of Tria. Littlefoot, meanwhile, goes off by himself, feeling very down about how "little" he is. As he returns to the treesweet tree, he climbs up the cliff right next to it and tries to reach the treesweets by himself. As he does, he accidentally falls right through the tree and knocks down every single treesweet. He finds himself surrounded by several miniature longnecks. They have eaten all the treesweets and quickly run away once the shocked Littlefoot starts screaming out of fear. Upon noticing that every treesweet is gone, all the dinosaurs in the valley are standing in front of the tree; they all suspect Littlefoot to be the guilty party. Littlefoot, afraid to admit it was his fault that the treesweets fell off the tree, blames everything on the tiny longnecks. Littlefoot falls down a pothole in the ground where, it turns out, the tiny longnecks are hiding in. First being afraid of them, Littlefoot flees deeper into the cave; but soon enough, he finds out that the tiny longnecks are not as bad as he thought and befriends them. Upon hearing how difficult it is for the tinysauruses to find food, he promises to help bring them as many treestars as he can every night. But he's still not sure how to explain their existence to the valley without getting blamed for the treesweets accident.

The Land Before Time XI: Invasion of the Tinysauruses was a good sequel, not the best but still worth the watch. Littlefoot is getting a little more mature with each story, I loved how he stood up to the valley and defended the little longnecks. The little longnecks were so cute and a great addition to the story. One story I did appreciate was the one between Cera, her father and Tria, a lot of kids have a difficult time when their parents split and start dating again so I think this was a good story to show. So over all The Land Before Time XI: Invasion of the Tinysauruses is worth the watch, it's a good sequel. So far it seems like the only reason people are complaining about these sequels are just because there are so many of them, my advice is to get over it, I'm glad I got into them. They are fun movies to watch for yourself, the family or your kids. I do recommend Invasion of the Tinysauruses, trust me, I'm always honest with the reviews.
