Hey sorry to disappoint you but there isn't actually a font for the Logo. Theres alot of similar fonts out there but nothing exact :(

Excuse Me, I made a font named Adventure Time and it's the exact look a like of it : http://www.mediafire.com/?0cbzjr319cru1o2

"File belongs to non-validated account"
aww :c can't download

finandjake - if you made a font - why not submit it to dafont...?

account is now validated
file can be downloaded

I submitted it but dafont has not yet verified that font

It was verified but it's too much low res, that's why it's not online...

If you could try to scan it in a bigger resolution before importing it and then make the .ttf, don't hesitate to re-submit it

Hello,maybe you can look for "Barbarian Regular" it is similar. Thers is a sword in the font.

This is concept of new font as Font Time (Part 1 and 2):
