A record heatwave strikes the city, setting everyone on edge. Arnold and Gerald look everywhere for relief from the soaring temperature, but finally snap when they learn the Jolly Olly ice cream man is price-gouging kids for his product. Arnold wakes to find the city covered in snow and hears that school is closed for the day. He wants to go out and join the rest of the neighborhood kids with their plans for snowball fights, sledding, building snowmen, and a big hockey game, but sees that Grandpa is saddled with extra work due to the storm. He volunteers to stay in and help out Grandpa with the chores.
