Harry is 'Jungle Harry', King of the Jungle and friend to all the jungle animals (otherwise known as the Dinos). The only problem is that they're not really in the jungle - they're in the hallway and disturbing Sam, who is trying to finish her homework. So they head to Dino World where they meet some real jungle animals who invite them to their Great Big Jungle Bash. The party preparations are going well until Leslie the LOUD lion arrives and scares away all the other animals. Luckily for Leslie, Harry and the Dinos stick around and try to find a way for all the animals to enjoy the Jungle Bash together!.
