Jimmy Neutron Easter Egg - SpongeBob Again

In the episode where Jimmy Visits the Bahama Quadrangle, go to the part where they go underwater. In the first underwater scene, in the bottom right corner, you see a rock, a tiki, and a pineapple, respectively. This is a clear reference and/or tribute to "SpongeBob SquarePants". Thanks to Nick's " Nick Extra" for showing me this egg.
