The front end of the Leap FrogZ is a little different compared to most popping frogs. It has a more aggressive cup to it, creating a pretty good chug on the retrieve. The bottom lip of the bait is shorter than the top and rounded which allows the bait to kind of dig into the surface of the water a little and then deflect the water off the top of the mouth to get the bait to spit a pretty good ways on the pop.
The line tie also seems a little higher in the mouth versus a lot of other frogs. The top lip comes together at a point and the line tie is kind of tucked up in it. This helps the mouth of the bait dig in when you twitch it with your rod tip down near the surface of the water. The line pulls down on the top lip and makes the Leap FrogZ an easy bait to work.
