I’m filling out my Pokédex in Ultra moon. I’ve been doing random encounters at Poni Grove where Riolu is supposedly a 10% encounter during day and night.

I’m at well over 100 random encounters and haven’t seen it yet.

In the time looking for it I have:

Watched all of Project Hail Mary

Found 4 Heracross in a row (also 10% encounter)

Found 3 Heracross in a row on 2 different occasions

Found 8 Pinser

Found a full odds shiny trumbeak.

I am going insane. Am I in the wrong area?? I’ve seen video footage of Riolu being encountered in the exact grass patch I’m resetting in.

Please send help
