Perhaps one could take the "batter" of pellets mixed with water and whip it in a mixer until reintegrated with air (or making the pellets less dense?) dry it in whatever shape you want. Adding egg white or a little yeast while mixing would allow the mixture to be less dense (or inclusive of more gasses). Either way I'm thinkin they will float. Anybody heard of 5 lb green sunfish crosses? Called the Kansas Kolossus...think I'm gonna get some...comes with free popcorn too...
Heck yeah. Fire up the griddle, grab the butter and maple syrup...nothing like a big stack of Aquacakes.... or flapmax....
I'm not familiar with the Kolossus, but I'm working on a Hoosier Humongosaur.....
