random organic forms

Hello people!

I'm kind of new to grasshopper, so I'm in the point of trying to learn its logic and strategies. 

So, I have this school project, for which I try to create a form that looks like this one. I mean not that complicated, but... you get the point! I tried metaballs but the problem is I cannot get a finished, smooth and clean surface, only this dirty and heavy mesh from points. So, does anyone have any idea of how this form could have been created?

Thanks in advance guys! It will be tons of help for me!
