Alex hides from Fiona Friend's gun-happy friends by concealing himself underwater in a lake, breathing through the hollow barrel of a shotgun.
By bracing himself against the sides of the chimney at Point Blanc Academy, Alex is able to climb up to the second floor.
To escape from Point Blanc Academy, Alex cuts an ironing board down to size with his concealed saw, and ties one of his trainers to the supports with bedsheet strips. He then snowboards to safety down the side of the mountain.
Dr Grief is making his escape from the academy in a helicopter, and it is up to Alex to stop him. Alex rides a snowmobile at top speed to the top of the academy's ski jump, then hurls himself off, letting the snowmobile continue on its way. Launched into the air at the end of the ski jump, it hits the fleeing helicopter perfectly, causing it to crash.
