Join Lil’ Iguana and his friends as they soak up the sun on a beautiful summer day. As the siblings participate in a friendly sandcastle-building competition, they’re joined by their neighbor Joe Jack, who invites Lil’ Iguana to join his family for a beach outing. With Momma Iguana’s approval, Lil’ Iguana eagerly prepares for the day ahead, packing essentials like sunscreen and snacks.

At the beach, Lil’ Iguana and Joe Jack encounter familiar faces and fundraising activities led by their friends Kelvin and Gigi. After supporting the soccer team’s cause, Lil’ Iguana and Joe Jack embark on a sandcastle-building adventure, demonstrating teamwork and creativity. 

However, their beach day takes a turn when Joe Jack suggests a shortcut through a dark alleyway. As Lil’ Iguana’s “Harm Alarm” signals danger, the friends navigate back to safety, reinforcing the importance of intuition and caution.

Back at the beach, Lil’ Iguana and Joe Jack’s sandcastle earns them a victory in the friendly competition, capping off a day filled with laughter, teamwork, and seaside memories.
