To be fair Rucker also has two daughters, so Thicke certainly has more going for him with his guess paired with the blowfish in the video and the “hoot” comment by Banana.
Darius Rucker was a good choice by Robin Thicke, though I’m not fully convinced he’s The Masked Singer’s Banana.
My guess based on the voice was Billy Ray Cyrus, and I felt extra confident when he started talking about his daughter being the inspiration behind The Banana.
If the next episode happens to have some vague references to the state of Montana though, you know who told you Cyrus first!
