Hi souljah I'll tell you what that is!!!! It's a toed or a snail, Im not posative what it is. Pritty sure it was a toed!! I went threw this problem years ago, only way I found out was I went out at nite and he dug up the soil to sit in the moister, if its a snail they dig in the dirt and lay eggs or something, one time my soil was messed up then the plant died a few days later when I dumped the soil there the bitch was!!
As for my lost plants, I don't sweat it. It sucks but I was over it by the time we got out of the mountain.
