Holy smokies... you know, you could always become a merman, Tazz.

Before I just outright DROWN (trust me, an Emolga never likes to scuba), I quickly teleport myself right back on the USS Jamboree Battleship, which I'm really grateful for right now. I quickly initiate the Submarine Transformation Sequence, and we head underwater.

I then use Displacement Field to start warping the water to other parts of the universe to drain it out. But... that takes a while. Your merfolk army tries to stop the process, but surprise! The USS Jamboree opens fire with two dozen harpoon gattling guns, which, to your army, is like trying to dodge hurricane rain. I then blow up your silly underwater castle with Ultimate Laughing Clown Torpedo, which laughs hysterically to the tune of carnival music just before your castle is blown to kibbles and bits. Har har, and you told me not to build real estate on the hill!

Displacement Field eventually drains the water levels to normal, now exposing the hill. I simply have the USS Jamboree enter Warrior Mecha mode, and decide to enjoy the hill and watch some Netflix.

I think I'll figure out the problem of worldwide merfolk later...

MY HILL!!!
