Mucktorok

is a TotK: in.

Characteristics
Mucktorok is a small Octorok-like creature, not much larger than a regular Octorok, which can create and control sludge. It uses this sludge to make a shark-like monster similar to a Series:, which it rides in battle. It is the source of the sludge that is polluting Zora's Domain.

Battle
Mucktorok hides in its sludge shark, and attacks with a combination of charging attacks, waves of sludge, and a sludge beam. The sludge shark resists most forms of attack, but Sidon's power or any water-based attack (e.g. any weapon Fused with an Opal) will wash away the sludge and expose Mucktorok. It will attempt to flee, but it can be stunned with an arrow when it does so.

At half health, Mucktorok will begin spraying sludge around the arena to slow Link down and make it harder for him to dodge its attacks; the sludge projectiles can also damage Link if he takes a direct hit. Additionally, Mucktorok will begin jumping between puddles of sludge when it is exposed, making it harder to hit.
