LOONA TV #70 is the seventieth episode of LOONA TV.
HyunJin tries imitating various TV characters: Patrick Star, Spongebob, and Himawari Nohara, though afterwards she becomes embarrassed. She then imitates HaSeul's "Seal~~~!" call from LOONA TV #48. HeeJin overhears this and does her own version, with HaSeul joining in too.
