"Holy Shit is that a Mosquito?" (3.5e Monster)

"Bert...wake up Bert...it's on mah face...I need hep dammit..."

All jungles have mosquitoes. Some of them have reeeeally big mosquitoes. Mosquitoes who are capable of defending themselves from fly swatters.

Combat
Mosquitoes plan to fly straight up, grapple, suck, and fly away as fast as they can. Then come back in a few hours if they're still hungry. If attacked they will fly away and follow the prey attacking again when it is unaware later. Damn skeeters...

Blood Drain: Each round the Mosquito has a victim Pinned in a Grapple it does 1 point of temporary Constitution damage. It will leave after it has drained 8 Constitution and become full.

Improved Grab: If the Mosquito succeeds with it's Proboscis attack it may immediately make a Grapple Check as a Free Action without provoking an Attack of Opportunity. Mosquitoes gain a +4 Racial Bonus to Grapple Checks.

Anesthesia: If the Mosquito attacks a sleeping or unaware victim (flat-footed) they must make a DC 12 Fortitude Save to realize the attack is happening due to the numbing effect of the Mosquitoes bite. Save DC is Constitution Based. Granted if they're awake the attack will probably become quickly obvious after that initial round.

Disease: West Nile virus—bite. Fortitude save (DC 12) negates; incubation period 1d4 days; initial damage 1 Dex and 1 Con; secondary damage 1d2 Dex (temporary) and 1d2 Con (temporary or permanent).

Improved Scent: As the Scent ability listed on page 314 of the Monster Manual, but the Mosquito can smell blood up to 1 mile away.

Skills: Mosquitoes gain a +4 Racial Bonus to Spot and Survival checks (+6 to Survival when tracking by Scent).
