Sia and NBA star Chris Paul are also here, for some reason

We’ve got a real Scooby Snack for you guys this morning: On Thursday, the Boomerang streaming service dropped the first-look trailer for new series “Scooby-Doo and Guess Who?”

The “Guess Who?” aspect of the show refers to each episode’s celebrity guest, which per the trailer, includes Ricky Gervais, Wanda Sykes, singer Sia and NBA player Chris Paul. In terms of the not-real-people cameos, Sherlock Holmes and Wonder Woman also pop up in the video preview.

Oh, and the ghost of Abraham Lincoln helps at some point. You decide which category that one belongs in.

Watch the trailer above.

The 13-episode “Scooby-Doo and Guess Who?” will begin streaming on Boomerang next Thursday, June 27. The weekly series will conclude on Thursday, Sept. 19.
