Maybe one of you can help me.
I am playing HeartGold and am trying to get an oddish for my team.

According to both Serebii and Bulbapedo, Oddish has a 60% chance of appearing at night in Ilex Forest and Caterpie has a 0% chance at night.

It's about 11:36 PM in my game
WHY THE FUCK DO I KEEP ENCOUNTERING CATERPIES!?!?!??!?!?!?
