Chaos erupts in Bikini Bottom with the LEGO SpongeBob SquarePants Build-A-Bob (3826-1) set, capturing a moment when Plankton seizes control of SpongeBob's brain. This sizable SpongeBob figure, standing over 11.5 inches (29.2 cm) tall, features play functions for interactive scenarios. Builders can animate SpongeBob, making him spin his eyes, launch jellyfish from his mouth, and change his facial expression from a frown to a smile. The set includes a Plankton minifigure, overseeing his machinations, alongside jellyfish projectiles. Internal Technic mechanisms drive these movements, enabling engaging, repeatable play within the model.
