Experiential learning and physical development center The Little Gym International is introducing SpongeBob SquarePants-themed Awesome Birthday Bash parties in partnership with Nickelodeon.

Available now at participating U.S. locations, the new SpongeBob SquarePants parties are designed for children up to age 12. The birthday parties will take children on an undersea adventure inside their local The Little Gym, as they engage with characters like Patrick, Squidward and Mister Krabs in an interactive story.

SpongeBob joins Dora and Diego, whose official themed parties were introduced at The Little Gym in 2012.

"Our member families have been asking for SpongeBob SquarePants parties, so we are excited to share the news that children are now able to experience 'nautical nonsense' at The Little Gym," says Ruk Adams, president and chief executive officer, The Little Gym International. "Through our partnership with Nickelodeon, The Little Gym is the only childhood development center providing families with Dora, Diego & SpongeBob-themed birthday parties that tap into the imagination and excitement of shows that children love."
