Things You Can Do As Two (Futari da kara Dekiru Koto - ふたりだから出来ること) is the 9th episode of THE iDOLM@STER anime series. It first aired on September 2, 2011.
After finishing filming a TV mystery mini-drama, Ryūgū Komachi and Ritsuko returns to 765 studios for a break with Mami and the Producer returning as well. Iori decides to treat everyone to some special pudding she bought and kept in the refrigerator earlier, but finds the puddings are gone. Suspecting the other idols as the culprits, Ami and Mami decide to solve the mystery by playing detectives. As the twins investigate and interrogate the others with their antics, Mami admits to the Producer she feels bored and lonely without her sister but hopes to be famous like Ami and be together again. After clearing almost everyone as suspects, the twins have everyone in the studio pull a scary stunt on Haruka, Chihaya and Miki which reveals Miki as the real culprit. With the case over, Miki explains she ate the pudding because someone ate her jelly dessert earlier that morning, which the twins inadvertently reveal they were the ones who ate it, much to the office's anger as the whole thing was their fault in the first place. Makoto also mentions noticing other things going missing from the fridge lately, which angers everyone else even further, causing the twins to be chased. In the epilogue, Miki reveals there was only one pudding in the fridge when she ate it as unknown to everyone, Azusa actually ate all of the puddings that morning despite being on a diet.
