Oh yeah, that's an Orange Ricky alright.
According To The NES Manual, Tetris Blocks Actually Have Names

According to this NES Tetris game manual that Twitter user vecchitto dug up, these are the names of the various Tetris blocks. And here I’ve been calling them L and backwards L blocks, when they’re actually Blue and Orange Rickys! I should have known. Hero and Smashboy are definitely the best names though, and I’m pretty sure a Cleveland Z is when you fart under the covers and then pretend to be asleep.

Thanks to my dad, who agrees now we need to use this knowledge to beat Tetris type B level 9-5 on the Game Boy to see the whole band play and the shuttle launch.
