what are the things in the jungle

Mind elaborating? Its kinda a vague question your asking.

Smiting gromo makes it so when ever something attacks you they take a small dot. Smiting krugs makes it so every like 5 auto attacks you stun the target. Wolves gives you something that gives vision of jungle. Raptors give true sight. Blue gives mana and red gives health.

Grump - fond of mushrooms which may or may not be harmful. He definitely is though. He will be the first to fall. Blue - blue is good for blue. He makes the blue bar go up, and lets you use more blue. Spoopy at level 1, not so bad at level 2. Puppies - a momma and her babies. Kill the babies first, it's the only ethical thing to do. Chickens - another momma hen and her chicks. Same tactic as puppies. And of course, everyone steals your chickens. Sometimes it's your midlaner, sometimes it's their jungler. WTB chicken wire. Red - red is good for red. He also makes your attacks red, which is a universal allergent. (My word, I made it up. Don't steal.) They will sneeze and cough if you hit them, which makes them easier to keep up with. Lugnuts - individually known as Lug and Nut. Lug's the big one. You might go a whole game without killing them.

Gromp - Poisons enemies that attack you for 90s if you smite it. Blue (Sentinel) - Restores 20% mana when smited, gives a buff when killed that gives increased mana / energy regen and 10% cdr Red (Bumbleback) - Restores 20% hp when smited, gives a buff when killed that gives a small dot on hit (Is the movespeed slow still around?) Krugs - when smited gives a buff that stuns the attacked mob every 6th basic attack or you can expend the buff to do extra tower damage Raptor - when smited lets you see wards within a area around you Wolf - Puts a little moving ward on your blue side that tracks enemies who come into your jungle

Baron Nashor - Gives a power increase and empowers minions near your character when killed. Rift Herald - Same as nashor except it drops a item that one person can pickup to get the buff. Dragon - Stacking buff dependent on the number of times you kill it (Look ingame I'm too lazy to type this one out)

As for what they do.. They're annoying neutral monsters spread throughout the jungle and river to give you buffs + gold + exp that sometimes kill you if you're not careful or mess up when attacking them.
