Unused predefined text cry command sound 0x16 (Dewgong cry)
Notes: Edit - Consider the Lapras picture a joke since the original pictures don't match in the first place (Game Freak used a Nidorino with Nidorina's cry). It's a Dewgong cry. This is in the code, so empirically it may not be noticed without the disassembly, debugger.. It was inspired by a recent video by Lowest Percent, discussing how you can't really beat Pokémon without errors (due to the wrong intro cry), and I was actually going to try and patch it and noticed this after looking into it..
The game uses different ways to play Pokémon cries; this includes predefined text cry commands to play Nidorina's cry (used during the new game sequence but an error; it is meant to be Nidorino), Pidgeot's cry (used in Saffron City text) and Dewgong (unused according to the Pokémon Red disassembly project). In this video I created two Game Genie codes to change it into Lapras with the unused Dewgong cry command 162-5C9-B3A and 131-6D9-7F4 (however, the palette still isn't fixed). I'm not sure if anyone knows why it's there, but we could guess it's for Lorelei's Dewgong, or really anything to do with NPCs or sequences with pictures?
