Release the first chain in the Basin
Close the Chalet window and operate the fan to thaw the lift. At the Terminal, use the Robombs to break the ice blocking the Gondola. Three paranormal chains now hold it in place. Follow the map to the chain-bearing ghosts, beginning with the Basin. Clear the Hiders before trying to reel in its Strong Gobber; the Gobber has three hundred health, so a clean repeated capture is safer than standing in its projectiles. The Prospector’s Crossing gem can be freed on the way by restoring the pickaxe, dropping one log on the ice and carrying the other onto it.
Clear the other chains and collect ParaBoola
In the Smuggler’s Hideout, restore the missing armor and close the window. Clear the Sneakers, then capture the Strong Greenie for another chain. Its health is one hundred. Descend through the Shaft to Deep Hall and restore the missing kettle above the fire. Blow it into place and wait for ParaBoola to emerge; this produces a Boo, not a rainbow. The Crystal Quarry E-Gate takes you back to the Chalet, where the landing knocks loose a gem. Clear the Greenies and capture the Strong Slammer, with two hundred fifty health, to remove the final chain.
Cross the High Wires and repair the generator
Use the freed Gondola’s coal shooter to melt the ice blocking the far route. Melt the ice supporting the tree on the left as well: the fallen trunk makes the detour to a High Wires snowball challenge and sapphire. Continue across the cables and narrow ledges to the Workshop Landing. The Workshop door lacks power, so enter the Maintenance Room and use the Robombs to break the ice around the generator’s components. Check which section remains covered before firing the next bomb. Once power is restored, return to the Workshop door to complete the mission.
