Golem cannot be caught in the Rock Tunnel. However, Geodude, which has Golem as its final evolutionary form, can be caught there.
Rock and Ground type
In Rock Tunnel
It is in Rock Tunnel.
You cannot catch a one, but if you trade a Graveler, it will evolve into a Golem.
You have to catch the Golem.
you get golem by link trading with a graveler but i dont know what you mean by golem trio
In the power plant which is below rock tunnel which is east from cerulean city.
it is in the commons up by the fairgrounds, go through the tunnel then you should be there.
I suggest you to catch a Zigzagoon because it can learn various HM's, including Rock Smash. If you really want to put Rock Smash on Golem or you don´t want catch Zigzagoon or something (i understand that), switch with Rock Blast (it's 2 to 5 turns, normally that type of attacks sucks :P) .
Where does GOLEM live answer!I am sorry but you can't catch the Pokemon "Golem" you will have to catch a Geodude (In the cave near Jublife) and train it to level 25 into Gravler and then trade it to evolve into Golem or just catch a Gravler (near Veilstone) and train it.-Buizelchuu(Please watch moar Krabz by Buizelchu on youtube)
catch a gravler then trade it
In the power plant its located sout from Rock Tunnel you need Surf to get there.
