Pink Bubbles Go Ape is the fourth studio album by German power metal band Helloween, released in 1991. It marked the departure of guitarist Kai Hansen, with Roland Grapow replacing him. It was also the first album released on EMI Records. The album contains two singles, which are "Kids of the Century" and "Number One". "Kids of the Century" reached #56 in the United Kingdom.
