Think

When Alphablock I's pen runs out of ink, Alphablocks N and K team up to make NK. Alphablock I makes more INK but causes a flood and needs to clear it up. Turning the ink PINK doesn't help. She contains it in a SINK but finds herself trapped in there with her friends. They turn the sink into an ice RINK. Everyone slips around, until Alphablock I has a THINK and comes up with the idea of ice skates. Now they can enjoy skating on the pink ice, and Alphablock I can THANK her friends for their help.
