OK, just talked to Exotic Nutrition on phone. They still make this product; but it's not in their webpage . Rep described it as 1/4 in. jelly cubes (99% water) medium. From description and pics, almost looks like a green version of Flucker's Kricket Quencher:

Also, he stated medium will dry; but can re-hidrate with spraying. Still sounds kind of strange to me and wonder how Pacman frog would interact and deal with it. I'm not experimenting with Fresita on this medium, so did not order any ($6 for 2 lbs.). If other members have experience with it please do share. Thank you !
