Digimon Adventure Episode 52

While MetalGarurumon and WarGreymon were fighting Piedmon, the latter pulled out a white cloth which he throws to grow and wrap his opponents in, turning them into keychains. He then does the same to Tai, Matt, Andromon, Joe, Izzy, Tentomon, Garudamon, Angewomon, Sora and Gomamon. TK, Kari and Patamon were the only ones left and defeat Piedmon, turning everyone back to normal.
