Kraken - Wall Skip

Late in Kraken's stage is a section with two of the colored gate switches over spikes. The speedrun can be seen skipping this through the wall using an invincibility trick.  This requires damage boosting. 
 
 Get on the right edge of the moving platform 
 As soon as it starts moving, dash jump to the wall, and slide down it 
 Your objective is to take damage from the electrical plug in the wall, then stand on the spikes with the invincibility frames until the platform arrives 
 When the platform does crushing damage, quickly jump up the wall and air-dash through the gate.
