With this vacation, you can enter Bikini Bottom and live amongst the characters. You can go to the Krusty Krab to eat Krabby Patties, go jellyfishing, and even visit Mermaidman and Barnacleboy's cave.

 

     If you purchase the Add-On, you will get to do all that and actually travel to Spongebob’s neighborhood to meet any of those characters and the actual voice actors
