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.

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.
