Nowhere.
You can find TM Dig at the Ruin Maniac Cave.
In Victory Road.
Mt.moon
dig
You would have to get it from firered or leafgreen the cool about firered and leafgreen is each can purchase the TM Dig at the Celadon City Dept Store then they can trade the TM to Emerald remember to trade between emerald and leafgreen or firered you must use wireless adapters.
This TM doesn't exist in leafgreen.
TM 28 is dig
first you need the TM dig and then you go to your bag and select the TM dig. then you select use and teach it to your pokemon
I think it's a TM or maybe something between lv.15 and lv.30
There is no Tm trick in leaf green
Nowhere.
Other Pokemon do know dig without the TM dig. Most DIGlets know dig. Find diglets in Diglet cave. Hope this helps!
you cant go underwater in leafgreen!!
