The Masked Singer season four kicked off on Sept. 23, and the competition is super fierce this year. Not only does this season have truly wacky costumes, but there are a handful of really talented singers. Seriously, they have really outdone themselves this year.

So far, we’ve been introduced to Group A and Group B, which include the first musical duo and a costume with a puppet. Ahead, keep reading for a breakdown of our thoughts, as well as who has been unmasked so far.
