They meet the captain who explains they are on a global tour before docking permanently in St Petersburg, FL. Bud wants to go on board but the captain declines citing ongoing renovation work on board. Porter takes the captain and two crew ashore to get supplies.
Meanwhile inquisitiveness gets the better of Bud and he gets Flipper to tow him out to the Bounty and he climbs aboard. After finding the Commander's cabin Bud falls asleep in a chair with a replica Captain Bligh hat on and dreams of adventures aboard. Meanwhile the captain returns and sets sail for the Canary Islands and Bud realizes he's trapped in the cabin and he breaks a window and sends Flipper to help.
Porter and Sand race to the Bounty and rescue Bud but he still persists in fantasizing on the way home thinking Ulla's mini sub is the Nautilus! Porter and Sandy say they'll have to monitor the books he reads!
