Screw Mobile is from this guide book: http://info.sonicretro.org/Sonic_the_Hedgehog_3_Koushiki_Guide_Book

All of the Sonic 3 boss names are from that book, including Big Arm, which was eventually used in-game in Sonic Generations 3DS. So they're the names that Sonic Team themselves consider the correct/official ones.

I strongly disagree with the idea of using the names only ever used in Sonic the Comic.
