Clefable cannot learn thief at any level, not even from the TM.
However it may use Thief if it knows Metronome, or a similar move.
Most dark types like sneasel or some psychic types like Abra some normal types like linoone and furret and clefable and wigglytuff can learn thief.
Lotad cannot naturally learn it but it can be taught Thief with a Thief TM. Lotad's evolved form Lombre learns Thief at Lv. 37.
Marshadow learns Spectral Thief at level 45.
To get more oran berries, you have to get a Pokemon that can learn thief or have pickup ability. Use thief when you see Teddiursa or catch Teddiursa to use pickup. Good luck:)
You use a fighting type pokemon. I suggest a manaky?
bannete or clefable
A keckleon in the wild already noes thief.
lv 1
Well, starly (or staravia) will eventually learn thief when leveling up. Personally, I I think Thief is a useless move.
Most dark types like sneasel or some psychic types like Abra some normal types like linoone and furret and clefable and wigglytuff can learn thief.
