Fighting Somnacanth at the Lava Caverns.

Do you hate falling asleep for no reason? Then you probably don’t want to be around Somnacanth because it loves breathing out sleep-inducing gas. As if Khezu wasn’t enough of a nuisance! When not sending you to la-la land, this sea monster also enjoys swimming around. Beware when it dives and resurfaces to show you a pretty shell–it can cause a pretty nasty bang.

Weaknesses

Somnacanth’s parts/elemental susceptibility.

Attack Patterns

Double Swipe

While on all fours, Somnacanth makes a high-pitched cry and begins to lift one of its forelegs off the ground. It’ll then swipe with that foreleg, move slightly forward and swipe with its other foreleg.

Torpedo Dash

While on all fours, Somnacanth crouches down and makes a quiet growling sound. The beast will then shoot forward like a torpedo. Whoosh! Despite the name we’ve given it, it can use this move on land too.

Sleep Trap

Somnacanth swims backwards and makes an eerie, high-pitched cry. It’ll then start leaving behind a trail of sleep gas as it swims, while changing direction, in an attempt to surround you with sleep gas. Afterwards, Somnacanth will move into the center of the sleep gas and use a Shell Bomb attack. Be sure to wiredash away at the earliest opportunity.

Shell Bomb

While swimming backwards, Somnacanth twists around on the spot, resurfacing with a big clam shell in its hands. It’ll then lean backwards, so its underbelly is facing upwards and clap its hands together. If the shell was glowing yellow, it’ll produce a flash bomb effect in front of where Somnacanth was facing. Otherwise, if Somnacanth grabbed a glowing red shell, it’ll cause a localized explosion.

Body Slam

While pivoting on its tail, Somnacanth claps its hands three times. It’ll then stretch up, before quickly slamming its body forward.

Spinning Pounce

While pivoting on its tail, Somnacanth makes a warbling noise and crouches down, like a pressed spring. It’ll then twist its body and leap upwards into the air, before pouncing forward.

Foreleg Sweep

While pivoting on its tail, Somnacanth makes a high-pitched cry and stretches out one of its forelegs to the side. It’ll then lean down in that direction and sweep its foreleg across the floor to the other side.

Head Sweep

While pivoting on its tail, Somnacanth flails its forelegs and head like it’s drunk or something. It’ll then sweep its head fin 360 degrees across the floor. Afterwards, Somnacanth will idle with its head fin out front–a great chance to attack it.

Mesmerizing Dance(?)

While pivoting on its tail, Somnacanth makes a warbling sound and stretches its forelegs down, so they touch the ground. It’ll then straighten itself, before shuffling forward and then performing a twist in the air.

Flying Darts

While pivoting on its tail, Somnacanth makes a short high-pitched cry and looks sideways. It’ll then twist its neck and shoot several darts towards the other side. These darts will remain on the floor for a while. Afterwards, Somnacanth will follow up with a sleep breath attack, which is aimed forwards. Once you’ve seen the flying darts, it’s a good idea to move to the side to evade this.
