Whether it was giving Aku Aku pop up text instructions, or replace a Crash smashing "death" that reminded them of the severed head and shoes left by a serial killer that was loose in Japan during Crash 2's release, we focused on Japan and fought hard for acceptance and success.”

January 7, 2013閲覧。 “Coco was created as a counter balance to Tawna who was Bandicoot's girlfriend. She came along because ND was sensitive to Sony Japan and wanted to please them. Sony Japan didn't feel comfortable with a super sexy character with Crash so ND went with a sister character instead to appease them. So here she is on the day of her birth. These are the first few sketches. This is where she started from. There's more and I'll be posting those in a later entry. I wrote down the date on these pages when I drew them. March 18, 1997. I was developing Crash 2 at the time.”
