"Come Out Henry" is the second episode of the first season.
Henry, the green engine, is afraid of the rain, thinking it will spoil his paint. One day, he runs into a tunnel and refuses to come out. The driver, fireman, passengers, and Sir Tophamm Hatt try everything to get Henry out of the tunnel (including getting Thomas to push him out) but Henry doesn't budge. They eventually give up on Henry, and brick him up in the tunnel. A sad and sorry Henry now wishes he hadn't been afraid of the rain.
