"Why?" Leo said "So you see what happens" David replies. David is trapped in a super bubble, until he unleashes his laser wrist watch to blast the bubble, the gang was shocked to see a weapon on David's wrist, Leo yells "Are you crazy? You've could've hurt us." David replies "I would've never harm any of you." his watch buzzes and it says "Attention: Lost treasure location in active Volcanic island." David says to June "You've wanna come to one of MY missions?" June tells David "OK" as he discovers that he doesn't have June's rocket shoes, so he carries her like a superhero to his castle for something. "You've don't feel airsick do you?" David says as June replies "No," David lands in the castle and June sees a lot of outfits in the hallway: A disco suit, a tuxedo, a pharaoh hat with cape, a pirate suit with hook and others more until David comes out in an adventurer outfit (Similar to "Indiana Jones") as he equips with a grappling hook, lantern hat-band, heat-proof capes and a watch communicator, "Let's go." David says, as both of them flying toward the Volcanic island. Will June and David find the island and the treasure?
