Schlitterbahn will debut a new attraction this Saturday that officials with the New Braunfels water park are calling the world’s first water coaster for kids. The Bow Wow Blaster coaster is part of a new children's area called Schatze’s Storybrook Park. The enclave includes six new slides, a 1,200-gallon tipping bucket and more than 70 interactive water features, spray toys and splash pads, according to the park.
