“From behind, one can see a view of SpongeBob's "brain", with Plankton controlling him, which was inspired by the SpongeBob episode "Plankton!", in which Plankton takes over SpongeBob's brain. This area contains various gears and consoles, with the gears providing... More interactivity.”

“The 445 piece LEGO 3826 Build-A-Bob set was released in 2006 and also contains a comic strip on the box. It’s one of the largest LEGO SpongeBob sets and hence the build will take some time, but the end result is fantastic!”
