Since TM34 did not exist in an official game where abilities existed, it has no official ability. However,
despite being a Glitch Pokémon, it may share some habitat characteristics with regular Metapod.
TM34 has no specific habitat because it was never programmed to be in a specific area, nor was it ever programmed for the player to find it. Since it only exists in Generation I, it must exist in the Kanto region. Theoretically, it could also exist in some Glitch City-like location.
