As I remember there was a kid who lost his monster (I think it looks like stone griffin) while he was searching for it he was helping other, in one episode he streamed (on TV I think) how to make a monster to a lot of kids next day all of those kids little monsters came to one place and made 1 huge jelly like monster. In another episode there was 2 sand monsters when they jump into one then they jump out from another one (they were teleporting). That is all I can remember, please someone help me find it.
