Pokédex entries

What each game says about it, in the games' own words.

Ruby	SHROOMISH live in damp soil in the dark depths of forests. They are often found keeping still under fallen leaves. This POKéMON feeds on compost that is made up of fallen, rotted leaves.
Sapphire	If SHROOMISH senses danger, it shakes its body and scatters spores from the top of its head. This POKéMON’s spores are so toxic, they make trees and weeds wilt.
Emerald	It loves to eat damp, composted soil in forests. If you enter a forest after a long rain, you can see many SHROOMISH feasting on composted soil.
FireRed / LeafGreen / X	It prefers damp places. By day it remains still in the forest shade. It releases toxic powder from its head.
Diamond / Pearl / Platinum / Black / White / Black 2 / White 2 / Y	It spouts poison spores from the top of its head. These spores cause pain all over if inhaled.
HeartGold / SoulSilver	If it senses danger, it scatters spores from the top of its head to protect itself.
Omega Ruby	Shroomish live in damp soil in the dark depths of forests. They are often found keeping still under fallen leaves. This Pokémon feeds on compost that is made up of fallen, rotted leaves.
Alpha Sapphire	If Shroomish senses danger, it shakes its body and scatters spores from the top of its head. This Pokémon’s spores are so toxic, they make trees and weeds wilt.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
