Heh. I've got a bit of a hobby of finding out if people are viable in the jungle or not in custom games - i.e. not just able to clear, but also able to actually pull off ganks worth the laners' time.

Some of my stranger picks that ended working were... Galio, Poppy of all people, and Urgot.

Galio's really mana hungry even with blue during his first clear, but still manages an average speed. Ganks are fairly dependent on landing Q, but with his E to speed up his laners, high base damages and ability to dive relatively early, he can pull off some nice plays if done well.

Poppy... tremendously mana hungry. If you use your W while you're clearing you might honestly oom even with blue. Ganks however are surprisingly good - much easier to force them into a wall with E if you're coming in from the side rather than from the turret. Or you can just knock them back towards your laner. Still mainly brings damage to a gank though. Main problem is lack of gold so I major in utility for her.

Urgot's early clear is really bad. Took me forever to set up masteries that let him clear in a bot game without a leash... The ganks are a lot of fun though - permaslow as long as your shield is up with some pretty brutal damage, and even an armor shred for if your laner's AD-reliant. I'd sum him up as being really vulnerable to counter-jungling, but a vicious ganker if he gets going alright.

Wouldn't say any of them were necessarily viable for ranked, but I've had fun with them all in normals at least, and contributed to my team with each of them - not just picking them because "it's only normal I can feed", but because they actually work to a degree.
