Mario vs Donkey Kong: (GBA) Undefeated Polterguy Bug?

This is a strange and minor glitch, that hasn't been documented yet, and it was found by me. As far as i know, this glitch can only be done on the 4th boss fight with Donkey Kong in Spooky House. It basically involves throwing an Shy Guy after he's been previously transformed into a Polterguy, towards another colored Shy Guy upwards below the platform. For the glitch to work, the Shy Guy must be thrown to another one at the exact height upwards or throw directly at him, which causes the Shy Guy (shown the yellow one here) to not be defeated offscreen, but strangely enough it still rewards 100 points to the score counter, despite the Shy Guy iself still been alive. (Note that the other thrown Shy Guy earlier falls off as expected) Normally, any enemy that can be picked up and thrown, is soppoused to be defeated upon colideding one to each other, but in this case the game dosen't realised the hitbox knockout disabled, and it makes the Shy Guy act as if wasn't KO'd at all. This also happens if you throw an Shy Guy towards another one, right as DK starts to activate one of the colored switch buttons that turns the other one into a Polterguy. Not really sure if this bug is mentioned before or not... (May not be an real glitch?) 🤔 #gaming #mariovsdonkeykong #gameboyadvance #glitches #supermario
