The Activity Club and the Ice Dungeon Challenge

Isaac heads for the chimney, dodging out of the way as Scrooge tries to tackle him. It will be difficult to check inside the chimney without trapping himself in it.

He doesn't have a chance to inspect the chimney because suddenly, Scrooge tackles him from behind. The two slam into the wall of the gingerbread house, which begins to crack. Isaac recovers before Scrooge does and realizes that the house is about to collapse. The roof is beginning to fall, and he steps out of the way. However, Scrooge, who has just gotten up, is still in the danger zone.

What should Isaac do?
