The adventure starts with Rookie saying he is ready to climb Mt. Blizzard, and that nothing can stop the expedition, but before he can finish talking, Jet Pack Guy shouts "ROCKSLIDE!" and the mountain shakes. He says the path up the mountain is blocked and he can't fly that high. Rookie is disappointed as he promised everyone footage of the peak. Jet Pack Guy tells him to keep training, and flies away. After this, Gary chimes in saying he can be of assistance, and tells the plater to meet him at his lab at the bottom of the mountain.
Once there, Gary says Rookie's expedition is of scientific value to him because he can scan the mountain from yetis, and offers to help if the player brings his scanner on the expedition. Rookie complies with the offer, and Gary says the scanner first needs to be tested for durability by going down a tube track with it. After reaching the tube tracks with the scanner, Gary says either track will work. While tubing down one of the tracks, the scanner makes various noises. Upon reaching the finish line, the scanner has broken. Gary is disappointing, and asks the player to return it to him at his lab so he can make adjustments. Upon doing so he gives the player a newer, more durable model. He says this one should be tested by being launched by geysers at the Beacon Boardwalk.
After going to the Boardwalk and being launched by three geysers, Gary asks to check the yeti scanner, and this time, it is undamaged. He then says it needs a power source, and ten crystal collectibles at the Sea Caves should work. Once ten crystals are collected they have to be brought back to Gary, who inserts them in the scanner. Gary asks the player to connect the wires, and after they are all put into place he congratulates the player on inventing the Yeti Scanner 3000 with him. He then says Rookie will be reaching the peak after all, and to prepare for an "explosive" ride. The player then receives the Ben's Bootsunique item, 100 coins, and 100 Rookie XP.
