Materials:

Hook: 3 or 4 X long streamer hook 4-14
Thread:  Chartreuse Flat waxed nylon ( F.W.N.) or Gudebrod Super"G"
Tail: Chartreuse hen neck saddle hackle
Body: Strip of 1/8" X 3/16" white Fly Foam for sz. 12 hook. Wider on large hooks.
Eyes: Small round head pins, yellow or red and Slick Fabric Paint. Black, Yellow, Red
Color: Marking pens, Florescent yellow for the belly and Pantone 283 for the top.

Tying the Froggie:

Step 1
Wrap hook shank to the bend with F.W.N. Tie in tail , shank length splayed,. Wrap F.W.N.  to the hook eye.

Step 2 
Tie in foam strip with "X" wraps 90 degrees to the shank on top of the hook just behind the eye leaving 1 1/2 shank length of foam strip on the far side of the hook. Wrap F.W.N. back to the tail tie in point. 

Step 3 
Take the strip that you left on the far side and fold it back ( parallel to the shank) against the shank to there tail tie in and tie it off with two wraps of  F.W.N. 

Step 4 
Fold the near side back and tie off with a whip finish. Cut the tag ends of the foam leaving about 1/8" beyond the tie off  wrap. Split these extensions vertically to make four little legs. Color the bottom Florescent yellow and the top with the 283 pen. I put black stripes across the top and spots on the bottom, the lines look like ribs in bright sun light through the foam. The pins are now shortened and stuck into the foam with Super Gell. Dot the eyes with Slick Fabric Paints. 

Step 5 
After the Froggie is good and dry, dip them in "Rain X", this will help keep the color on longer.Colored foam can be used instead of white. I have used green, yellow, gray (for mini froggies), orange and black. The black has done well in daylight or dark.
