The Knott's Berry Farm (KBF) Discussion Thread in Theme Parks, Roller Coasters, & Donkeys! Posted November 2, 2016 I'll never be happy until they bring back Hammerhead I loved Hammerhead, but I was devastated when they removed Tampico Tumbler. RIP Don't forget Gran Slammer! Love that ride too along with Hammerhead! Unfortunately Tampico Tumbler was removed before I was tall enough to ride it!
