this frog is really a soft plastic frog but is does have a hollow body , the CANYON PLASTICS 4.5'' frog is the best frog ever !!!! i have recently been posting about the RAGE TAIL TOAD as being the top frog but the canyon plastics frog is a little heavier so you can cast alot farther , it has a pointy nose so that when you pause it , it wil sink and then you can twitch it like a fluke and get some super action !! you also can run it real slow cause it has slim legs that move good with not much speed . i used to use these years ago , i got them from a tackle store that has since went out of buissness , so when i went to a tackle shop that i haven't been to before i only grabbed three packs , and four packs of rage tail toads , needless to say i'm gonna keep two packs of rage tails but return the other two and get more ( all they have ) of the canyon plastics frogs . so long story short , if you love frog fishing like i do , give these a try , i swear you will LOVE THEM !!!!! 8-)here is the link for them - http://www.***.com/descpageFROGSCP-CPF.html
