Hi! im a jungle mainer Gr0tRid3r( EUW ), been playing about a year and got to S5, My mains are Udyr, Mundo and amumu, sometimes Master yi. The first i discovered jungle was at lev 13 where i had to jungle with shaco, it went decentm, won the game and got honored. I like champs that have great sustain in jungle and clear fast like udyr, or offer much in teamfights like amumu, other then that some damage is good too like rengar or kha'zix.

Start the Golems, move to Red Buff then raptors, wolves nad then recall, take gromp, blue and gank mid or top

Mundo is a HP Beast! you can basicly 1v2 anyone thx to your ult and W + E, Mundo can clear jungles pretty fast cause of your W, Early game is a bit hard bcause of your health loss but if you get cinderhulk you are fine longer on. Gank at lev 4 and gank mid or top, slow with cleawer toggle W and close up then e, if you gonna 2v2 then toggle r(Including running away from 5v1, toggle r and keep throwing E).
