Guacamelee! Super Turbo Championship Edition

Chupacabra's are the first flying enemies you meet in the Desert area. You need to kill one using only DOWN + B (Frog Slam).

Try to lure one towards a hill so you can jump above it. I got it in Forest De Chivo as it has some nice hills to jump off.

Like FailedSeppuku said, this is easier if you have a higher ground near you.

The video starts when you enter the desert (Desierto Caliente) first. There are some enemies you have to get rid of first. Once they're gone you can use the step to lure the chupacabra to the left and take him out with 3 frog slams (down + B).
