1) Ok, first you get a rectangular sized paper like the pic from above.
2) Then you fold the top diagonally one way in to the other side.
3) You do this again to the opposite side.
4) It should look something like this. With a creased "X" in the middle. K, with me so far? Where the arrows are pointing, you fold them down inside.
5)Like the pic above, that's how you should fold it.
6) Then, flatten it out.
7) Fold part of the flap up, like into a triangle shape. And do it to the other side the same way.
8) It should look like that. Two flaps up.
9) Where that arrow is, that means to fold that side into the very middle of the frog. (as shown in the pic)
10) And it ends up like this. Er.. yeah..
11) Take the top two flaps, and fold down the top of the points, to make into frog arms or legs... whatever you call them.
12) Where those lines are is how you fold them into different parts (follow the picture's directions)
13) Turn it over, and the frog will (..erm.. if you did it right) looks like that. Where the arrow is pointing, you lightly push down, to make the frog hop.
