Pokémon Adventures
A Shaderoot Carrot first appeared in PASS38, where Calyrex grew it from the Carrot Seeds planted by Henry, Bede, and Peonia at the Old Cemetery. The scent of the carrot caused Spectrier to appear, though it was unable to recognize where the scent was coming from and ran past the group.
In PASS40, Bede placed the Shaderoot Carrot in a bowl at the Crown Shrine to lure Spectrier there. As soon as Spectrier arrived and spotted the carrot, it ate it, giving Calyrex an opening to use the Reins of Unity on it.
