Official Rare Banjo Blog:
"With only a week to go before the release of Banjo-Kazooie: Nuts & Bolts, the editor has posted a brand new edition of everyone's favourite Q&A, Scribes!
With help from a few dev team members, the editor answers all your pressing questions including these:
I was just wondering if the feathers on Mumbo's head had flying properties like Kazooie's? I mean did he rip them from Kazooie or something?
Bryner
Editor Answer - Possibly. Maybe he sliced her head open like Sylar and now he can do a Flap Flip jump as well.
I can't wait for Banjo-Kazooie! I literally crapped my pants when I heard the big news. I'm also looking forward to Nuts & Bolts but I want to try the demo first (make it happen please).
Christopher 'Chito' Escobar
Editor Answer - Everyone's having accidents in their pants today. Demo's up now, stop cacking yourself and play it.
