It was the last morning that Andrew, Judy, and Thudd were in Hawai’i. Andrew helped Uncle Al finish his new invention, Water Bug.
The Water Bug was on autopilot, and it tilted down and dove under the waves.
They called Uncle Al for help.
A hammerhead shark cruised around the Water Bug.
The hammerhead shark attacked the dolphin's calf. The Water Bug popped out the Bug-a-Boo. It made the Water Bug look scary.
The sea stars ate lots of coral animals, so the Octo-Tool of the Water Bug plucked the sea stars off the coral.
Soggy Bob in the Crab Mobile was using an eel to swim in a circle around the Water Bug.
Water Bug jetted away from Crab Mobile by the Escape and Ink Jets.
Suddenly, there was an eruption of the underwater volcano.
After that, Super Sniffer was stuck with the lava boogers. Andrew and Judy who were in the Bubble Duds tried to pick the lava boogers out of the Super Sniffer with Nose Pick. Something with a strange sound was coming up behind them.
