Mugo is really good compilation youtuber. Mugo has created other videos like where he put the dream team into a icarly intro or made an ad with dream and george being next door neighbours to someone else which I found really funny. I will link some of his videos. Most of these people are doing no harm. Dream himself likes it and says they are super hilarious he mentioned space croissant who seems like a nice person
Yes, I agree there are others leaching off dreams content that might seem a bit fishy but most of them are fine. Also don't mention other people please check f their channel before you call them out or don't call them out at all.

Here is the icarly vid i mentioned editing videos is really hard especially making a icarly intro into your own version is really impressive. The video itself was pretty funny. Please check it out if you can it might change your mind.
