Feeling homesick, Boomer and Brady call Aunt Nancy and Uncle Bill to check in, but accidentally end up scaring them with their tales of Tarantula people, quick sand and giant bugs. While Aunt Nancy and Uncle Bill rush to the island to bring the twins back to Chicago, Brady is accidently stung by a dangerous Waka Waka bug. With the help of Mason and Mikayla, the kings must hide Brady's strange side effects including pumpkin head and amnesia in order to prove that the island is safe enough for the kings to stay and rule. Meanwhile, Mason has a date with a girl named Stewy.
