Angela's birthday is coming up, and Zack wants to take her out. He arranges a nice double date with Tommy & Kim and her at a fancy French resturant. He seeks a pair of pearls earrings to give to Angela, but is unable to afford any. Zack finds a strange hustler at the park, who gives him a pair real cheap. It turns out, the hustler was a putty in disguise, and the pearls are the evil Pearls Of Stillness!
Angela happily puts them on, and freezes everyone in the resturant. Zack & Tommy are the only ones unfrozen, and must fight Rita's Oysterizer monster to undo the pearl's effects. The duo do so, but Angela's angered about the disintergrating earrings. The Rangers, in the Megazord & Dragonzord, take on Oysterizer under water! Later, Zack sings Angela a ballad, with Bulk & Skull providing the music.
