If you've ever played the classic Crash Bandicoot game on the original PlayStation, you'll know that there's a mask called Aku-Aku that you can get in the game, helping you on your journey and playing a part in the narrative. He's got a classic noise he makes too, and if you've ever wondered how to spell that, US retailer Macy's might have the answer.
Macy's online store lists a t-shirt for sale that has Aku-Aku on with "Oodibigah!" above it, and while this isn't an official set-in-stone confirmation of the spelling, it's very plausible.
Elsewhere NeoGAF user wrestleman has compiled a list of other Crash Bandicoot merchandise emerging before the releasing of Crash Bandicoot: Nsane Trilogy next month. Did you think the Aku-Aku catchphrase was spelt like that?
