North Tower

The North Tower was one of 4 Toad Towers in Amphibia and is presumed to be Captain Aldo's tower. It was later destroyed by King Andrias.

Background
Sasha, Grime, Percy and Braddock arrive at the Toad meeting to pitch their idea of taking over Newtopia and Amphibia. Everyone likes the idea, but don't want Grime to lead. Sasha impulsively takes the challenge of acquiring Barrel's Warhammer to prove their worth and trust. Despite Percy and Braddock saying they should quit if things got too dangerous, Sasha ignores their pleas and together they face the giant worm to get the hammer back and to prove that she can make it without Anne or Marcy. Though successful, it let to Percy and Braddock leaving, unwilling to work with Sasha, much to her depression.

In "True Colors", King Andrias used the recharged Calamity Box to power an energy-based cannon on top of his castle in midair above Newtopia. The cannon once powered up quickly destroyed the tower into pieces with an earth shattering explosion to show the power he now wielded after Anne and her allies told him he would be stopped.

Appearance
North Tower is essentially a dark and cryptic castle made of stone bricks and decorated with giant bird skulls and bones.

Trivia

 * In "Barrel's Warhammer", it's revealed that there are 4 towers (one of the 3 are North itself, East, and West), with Toad Tower being the South Tower.
 * As of "True Colors", North Tower gets destroyed by the energy-based cannon on top of Newtopia Castle fired by King Andrias while flying in midair above Newtopia. It is unknown if any toad soldiers at that said tower survived after the blast, although only one male toad manages to see the shot coming and escapes out of the tower just in time before it got blown to pieces.
