Lorelei pokes the rock with her wand. She swishes and points her wand at the rock, and says "Variegatus". Nothing happens. She clears her throat. Swishes and points again, "Variegatus" she says again. The rock shook a little, but nothing else happened. She looks around, seeing the other rocks already turned into pitchers. She concentrates harder, looks and points at the rock, "Variegatus". The rock morphed into a a pitcher, but only for an instant, and turned back into a rock again.
