The Calamity Box is a music box invented long ago by Valeriana that using the Calamity Gems' power, can enable interdimensional travel to Earth, Amphibia and other dimension/worlds/planets. It was later held in the store Thrift Stop before being stolen by Anne (unwillingly) on her 13th birthday. It was destroyed after using it to teleport Anne, Marcy and Sasha back to Earth, as the box with the remaining three Calamity Gem shards was opened by Valeriana. A long time ago, the three Calamity Gems were used to in the creation of the Calamity Box by the wisest Newt of them all, named Valeriana, who used it to unite the kingdoms under one banner. Its purpose manifested into interdimensional conquest and ambition, leading Amphibia to a golden age of peace. However, Valeriana was burdened by guilt and sadness over the sight of conquest and subjugation on other worlds, placing her on a long quest for redemption for what she's done. The box was then left at the hands of Newtopia's royalty. According to research done by Terri in Escape to Amphibia, Aldrich's ancestors used the box's music as coordinates to travel to different worlds. This resulted in the ancestors conquering them by stealing all of their resources and some of its inhabitants, leaving the planets lifeless afterwards.
