Snow Base — Frost Walrus

Frost Walrus's stage, Snow Base, is an arctic Repliforce base built from ice — slick floors that kill your traction, crumbling ice platforms that give way after a moment, and freezing water sections that sap your footing further if you fall in.

Right at the start of the stage, climb the ladder to the upper level — you'll see a frozen block up there. Break it with a fire attack (Rising Fire) so it falls and frees the Heart Tank.

Right after you drop down the first collapsing ice slide, look for a high ledge on the right. Use Lightning Web to reach it. Grab the EX Item and you'll always start this stage with 4 lives instead of 2.

At the start of Area 2, take the upper route — the Weapon Tank is frozen inside a large ice block. Break it open with a fire attack (Rising Fire) to claim it.
