Wonky new Dendrobium Phal growth

[Erica0227]

Hello, so, I know that dendrobiums usually grow from little small sheaths on the side of the canes. Correct me if I'm wrong. I had a sheath, then uhh, a little child not to be named, peeled it. At the same time, it also had what is in the picture but smaller. I'm pretty sure this is probably very normal and common but I don't really know what that green thing is. Any help would be greatly appreciated.
