The Ice House Skating Rink is an ice skating rink in Dimmsdale. Timmy goes there for a school trip with students of Dimmsdale Elementary School.
The students of Dimmsdale Elementary School go to this building on a field trip or on a school dance. Among the ones present are Timmy, A.J., Chester, Trixie, Veronica, Mark (in alien form), and dozens of unnamed boys including a French foreign exchange student.
The building is shaped like an igloo. Inside is an ice skating rink. Occasionally, a heart-shaped disco ball drops from the ceiling when it is time for couples skating. There are also several school buses in the parking lot, meaning the children came here as a part of school. (Further evidence that this story is a school trip is his wish to be "the only boy at school" which removes all the boys).
This ice rink would occasionally have couples skating. Timmy always wants to play with Trixie Tang and goes to ask her to skate with him, but other boys get in his way. Timmy tried wishing that he was the only boy in his school, but this left one boy who is not from his school, and who asks Trixie first. Timmy then tries wishing that he was the only boy on Earth, but this left the other intelligent life forms (like Mark) on Earth able to ask Trixie. Timmy gets a bit more specific and wishes that he and Trixie were the only two people on Earth besides Cosmo and Wanda and Trixie did not question why. After everyone was gone, Timmy and Trixie left the ice skating rink. Unfortunately for Timmy, the wish slowly began to backfire on him as Trixie soon became more psychotic as time passed due to Timmy being the only person/life form on the Earth for her. As a result, she nearly tries to kill him when he breaks up with her.
