Wet'N'Wild SplashTown added a new ride on June 16. Alien Chaser is a six-story slalom and 429-foot tube slide. Riders slide down purple and black tunnels into alien-themed saucer structures.

The 80-acre water park at 21300 I-45, Spring, is open seasonally through Sept. 23. 281-355-3300. www.wetnwildsplashtown.com
