Dora and Diego travel back to prehistoric times and go on a dinosaur adventure to find Baby Jaguar and bring him home to his birthday party.

Dora, Boots, and Abuela are exploring the rainforest, looking for the secret door to Adventure Forest. It's a magical forest amusement park that Abuela used to go to when she was a little girl. Her favorite ride was the Roller Coaster Rocks, which she's always dreamed of riding one more time. While now at Adventure Forest, the group rides tea cups and log rides, and swings through trees on their way to the Roller Coaster Rocks!
