Angry Birds: Land Before Time is a video game made by Rovio and Steven Spielberg Films.
All the dinosaurs from Land Before Time went to a time machine and go to the modern world where they meet the Angry Birds. However, two egg eaters Ozzie and Strut stole the birds' eggs and team up with the pigs to build fortresses to avoid the birds from getting them back. Other dinosaurs (like Petrie's parents and Sharptooth) also stole the birds' eggs for food and team up with the pigs to build fortresses.
