people are calling a lot of different things frogspawns these days... Generally if i see that the tips are round, i call it a torch. If there are multiple tips per tentacle then its a frogspawn. If there are single tips but they are oblong, then hammer.
But recently ive seen a lot of people selling "frogspawns" that just have one tip per tentacle. Its a euphylia, treat it as such xd
