Zombot Sharktronic Sub

"The ravenous engine of carnage from the murky depths."

- First heading of the Zombot Sharktronic Sub's Almanac Entry.

"The Zombot Sharktronic Sub is a true labor of love. Dr. Zomboss obsessed over every detail of the aquatic mechanism of doom as he worked on it day in and day out from the wee hours of the morning until well after dark. He carefully handcrafted the shark's nearly impenetrable skin. He shaved each razor-sharp tooth to a point by hand. And he painstakingly installed the lethal plant-consuming fan inside the machines' horrific maw all by himself. Zomboss shed more than one tear of joy when his masterpiece was complete. Say what you will about the evil genius, but he is quite passionate about his projects."

- Second heading of its Almanac Entry.

The Zombot Sharktronic Sub is one of the robots created by Dr. Zomboss in Plants vs. Zombies 2. Like all other Zombots, it was used by him to defeat the players and eat their brains in Big Wave Beach and Modern Day.

History
The Zombot Sharktronic Sub was first introduced in Big Wave Beach - Day 32 as a boss. The players had to use Big Wave Beach plants (Lily Pads, Tangle Kelps, Bowling Bulbs, Homing Thistles, Guacodiles, and Banana Launchers) to fight Dr. Zomboss with this robot. After the robot was defeated, its sharp teeth and fin fell out, with the beach water filled in Zomboss's cabin, and he can be seen saying something inside. When he teleported away, the players earned a Big Wave Beach trophy (a  bag when replayed) as a reward.

In Modern Day - Day 33, when the game picked the Big Wave Beach boss fight, Dr. Zomboss resent the Zombot Sharktronic Sub to fight the players. They had to use Lily Pads, Pepper-pults, Chard Guards, Stunions, Rotobagas, and Shrinking Violets to fight him. Zomboss summoned the same zombies and performed the same attacks from the previous level. After he was defeated, the players earned a Modern Day Pinata (a money bag when replayed) as a reward.

The Zombot Sharktronic Sub takes the form of the shark with yellow eyes. It has sharp jaws and a mouth turbine to pull plants and zombies and then instantly kill them. Dr. Zomboss is encased inside a glass tank with an antenna on top of it.
