unknown bodies in cell culture - (Apr/03/2015 )

I've recently started a HaCaT culture, and I noticed some strange blob-like things in the flask. I really have no clue what they are, so do any of you know? I'm attaching a picture; the bodies in question are in the red boxes. I was wondering if you could tell me what's going on in the yellow box as well, though I'm not so concerned with that one.
Sorry if it should be obvious or anything. I'm new to this.
Thanks.
