The Crystal Gems are going to get a little bigger when Steven Universe returns; the Cartoon Network favorite is introducing a new Crystal Gem as well as an all-musical episode.

Steven Universe has shifted to an erratic episode schedule recently, but its upcoming event Steven Universe: Summer Adventures will air a new episode every single weeknight for 4 weeks. Yup, you did that math right — that means there will be 20 new episodes airing between Monday, July 18 and Friday, Aug. 12.

Toward the end of the event in August, fans will meet Bismuth, voiced by guest star Uzo Aduba (Orange Is the New Black). The 22-minute special “Bismuth” will introduce the purple, rainbow-haired gem, who fought alongside her fellow Crystal Gems in the battle to save Earth over 5,000 years ago. Get your first look Bismuth’s reunion with her friends in the exclusive clip, above.
