This scared me more than Saw IV. This is the only thing that's ever given me nightmares. They're like children no-one wanted that have grown up in Madagascar!!!
It's an Aye aye. I remember seeing one for the first time on TV a few years back. They tap on trees with their long finger (which is a freaky feature) to find the where abouts of bugs. Then they hack through the hollow bark and use that long finger to go in and scoop the bug out...
If you're posting scary things (lol Saw IV, them films just don't scare me but they shock the face offa me) then look up Mel's Hole and the Hole to Hell hoax. Yea sure they're both hoaxes but 4am and the hole to hell sound sample don't mix!
I like the hole to hell one because I went to the Kola borehole when I was a kid and it was maaaaassive. Like someone had just pulled a tectonic plate from the earth.
