Welcome to my jungle build.
I create this build because teemo is so fragile.
Thats why im lvling up him in jungle and he is a swift ganker Move quick ability.
Maybe u need some practice to be successful dont give up so early.

starting with red u must have toxic shot
after red u can go for ganking red+ toxic shot+ exhaust =gg
after gank continue with wolves - wraiths
u must be lvl3 now go for another gank and continue like that but dont forget to take red buff every 5 min

*******pros*******
-high speed ganker
-natural warding
-stealth
*******cons*******
-easily focus
-they can counter with 400gold oracle
-he don't have bursting skills

always communicate with your team mates or leave the game
you have to work as a team because your champion is team supporting fighter
do not beam people in your team or you lose
DON'T FORGET win-lose just about psychological
and don't expect that you can win a game after you fail
thats why always stay tuned and be confident.
