This has been done in various ways with:

- Luna, who can jungle with early glaives and abusing aggro resets - [YouTube Guide](http://www.youtube.com/watch?v=8xpDLRShttY)
- Medusa, who can kill Radiant ancients with split shot - [YouTube Guide](http://www.youtube.com/watch?v=9NoHaYnCShM)
- Tinker, who can kill ancients with March - [YouTube Guide](http://www.youtube.com/watch?v=vzlCAtZoE7g)

The problem with all of these heroes is that it's very easy to shut them down and steal their farm, and it's very conspicuous as none of the heroes are viable roamers or gankers early in the game. Jungling usually means doing so from level 1 and keeping pace somewhere between a dual laner and a solo in terms of experience.

To be complete, the following heroes can jungle reasonably well:

- Axe
- Batrider
- Chen
- Doom
- Dark Seer
- Enchantress
- Enigma
- Lifestealer
- Lone Druid
- Lycanthrope
- Nature's Prophet
- Ursa

The following heroes can jungle if it's absolutely needed but they're slow at doing so and thus probably shouldn't:

- Bloodseeker
- Huskar
- Phantom Lancer
- Shadow Demon
- Skeleton King
- Troll Warlord
