Algitt

Camouflaged as rotten kelp, they spray liquid poison on prey that approaches unawares and then finish it off.

It looks just like rotten kelp. It hides from foes while storing up power for its evolution.

It vanishes into seaweed and remains perfectly still to avoid attacks from large Pokémon. Rotten seaweed is its main food source.

It’s not good at swimming, so it clings to the seaweed. In the Alola region, it’s often found near Dhelmise.

It drifts in the ocean, blending in with floating seaweed. When other Pokémon come to feast on the seaweed, Skrelp feasts on them instead.

Skrelp looks like a piece of rotten seaweed, so it can blend in with seaweed drifting on the ocean and avoid being detected by enemies.
