This newly discovered glitch was discovered by me!!
i call it the reverse fishing glitch
this glitch does this:
instructions:
1. stand the way the picture bellow is showing ( i havnt tested it at any other locations..)
2. get on your bike
3. get off of your bike, your partner pokemon should still be gone
4. walk to the left, your partner should now be to your right
5. walk to the right so you switch places with your partner
6. Start fishing, when you catch fash your partner pokemon will get an exclamation mark above their head instead of you.
idk if this is a proper glitch or not, but im just showing you so you know about it :)
and idk what the translations are so dont blame me if this dosnt turn out to be a glitch

for the lulz:
