While Walker was fully focused on manipulating the ice, the king was rushing to get on to and attack where he believed the core of the golem and the slime fusion was. The slime tentacles that had peeled away from the golem would normally have whipped around at the king, but they were slow from the col and partially frozen.
"Walker, make me some spiky gauntlets again!" Remey was the only available person to push up and help the king. If she drew the attention of the slimes' attacks she knew that the king could attack the core and finish the monstrosity they fought.
Walker manipulated for the ice to wrap around Remey's hands as she climbed up the golem and stood on top. The slime tentacles noticed her and attacked her instead of the slower moving dwarf king.
Wonder what the king found...
