The Land Before Time XI: Invasion of the Tinysauruses is a 2005 direct-to-video animated film and the 11th film in The Land Before Time series. It was released on January 11, 2005, by Universal Studios Home Entertainment.


Every year, as the warm season approaches, a tree in the Great Valley blooms with pink flowers. These "treesweets" are viewed as a delicacy by the dinosaurs. However, because of the tastiness of the sweets, and due to the fact that there seems to only be one such tree in the valley, there is hardly enough for every dinosaur. Because of this, none of them may eat the treesweets until "Nibbling Day", when they reach the "peak of their tastiness".

Mr. Threehorn is visited by an old friend, a threehorn named Tria. Topps promises Tria the first treesweet of the season, and Cera becomes jealous. Cera refuses to make friends with Tria and dismisses her. Cera also becomes violent toward her friends when they make any references involving Tria. After being teased for his height by Cera, Littlefoot sulks about how "little" he is. Despite "Nibbling Day" not having arrived yet, Littlefoot goes to the tree, climbs the cliff next to it and tries to prove that he can reach the treesweets himself. While doing this, he accidentally falls through the tree, knocking down every single treesweet. Distraught, Littlefoot faints. After waking up, he finds himself surrounded by "tinysauruses," miniature longnecks. They have eaten all the treesweets and run away once Littlefoot starts screaming in fear.

Noticing that every treesweet is gone, everyone suspects that Littlefoot is responsible. Fearing he will be banished from the valley, Littlefoot makes a parish truth and blames nearly everything that happened on the tinysauruses. At first, everyone laughs at him, but then believe him when they find teeth marks on one eaten treesweet that are too small for Littlefoot to have made. Everyone begins looking for the tinysauruses, thinking of them as pests and preparing to drive them out of the valley. While searching the valley, Littlefoot falls down a pothole and finds tinysauruses' hiding place. Despite being initially afraid of the tinysauruses, Littlefoot soon finds them to be nice and befriends them. Upon hearing how difficult it is for the tinysauruses to find food, Littlefoot promises to help bring them food every night.

Littlefoot's friends find him while he is bringing food to the tinysauruses. They also fall in the pothole and, upon meeting the tinysauruses, agree not to tell the adults. The tinysauruses' leader, Big Daddy, distrusts the Great Valley's larger dinosaurs. He thinks they believe that "because they're bigger, it makes them seem more important". By morning, Cera decides to be friends with Tria.

When sneaking off to see the tinysauruses the following night, Littlefoot and his friends are discovered by Topps, who is on guard duty and sends them home. Afterwards, he meets up with Tria and they spot two tinysauruses, Lizzie and Skitter, who have been waiting for food. A chase ensues that ends when Topps and Tria, who is trying to stop him, find the tinysaurus colony. Topps gathers the other adults to let them know that he has found the tinysauruses. As the grown-ups prepare to block the caverns, Littlefoot stops them and fully admits what actually happened with the treesweets, involving how he first knocked them off. The adults forgive him and decide to leave the tinysauruses alone. But the tinysauruses' cave then collapses.

The tinysauruses escape into the Mysterious Beyond, and encounter two Utahraptors who chase them back into the Great Valley. Upon hearing that Littlefoot initially blamed everything on the tinysauruses, Littlefoot's friends become upset with him. Angry at his friends' rejection, Littlefoot decides to set things right on his own. Meanwhile, Cera apologizes to Tria about Topps being hard on her when she tried to stop him from hunting the tinysauruses down. Meanwhile, Petrie, Ducky, and Spike feel remorseful for making Littlefoot leave. With Cera's help, they all try to find Littlefoot but mistake the sharpteeth for Littlefoot, and the two carnivores chase them through the Great Valley. Just as Ducky is about to be eaten, Littlefoot saves her. Topps and Tria also appear. The tinysauruses then come to the children's aid and fight the carnivores. The grown-ups of the valley reach the group and drive the sharpteeth back into the Mysterious Beyond through the same hole, which they cover up with a boulder to prevent them from coming back.

With everything sorted out and friendships repaired, the tinysauruses then become residents of the valley. When Nibbling Day comes, Littlefoot reaches the treesweets by himself. All the dinosaurs share the tree sweets, learning how even small things can make a big difference.

The music score was composed by Michael Tavera. Some of his arrangements of James Horner's original themes from the first film can be heard in two shots of the film (one where Ducky, Petrie, and Spike tell Littlefoot why they are mad at him and the other where the Sharpteeth come out of a cave), though Horner was uncredited in this film. This was the last time that Tavera's arrangements of Horner's themes was heard in a Land Before Time film, as Horner died in a plane crash on June 22, 2015. Tavera's older themes from previous sequels can also be heard in other scenes from the film.

The music that plays in the background when Topsy catches Petrie trying to get one of the blossoms is the booby trap sliding scene music from An American Tail: The Treasure of Manhattan Island.

All tracks are written by Michele Brourman and Amanda McBroom.

1."Creepy Crawlies"John Ingle, Camryn Manheim, Tress MacNeille, Miriam Flynn, Kenneth Mars & Jeff Bennett 
2."Girls and Dads"Anndi McAfee & Cree Summer 
3."If Only"Aaron Spann & Kenneth Mars 
4."Stupid Stompers"Michael Clarke Duncan, Cree Summer, Nika Futterman & Leigh Kelly 



The Land Before Time XI: Invasion of the Tinysauruses is considered by many critics and fans to be among the worst in the series alongside The Wisdom of Friends, with many citing a confusing storyline and poorly-written songs.
