Petal Pals are a collectible pull-string doll quintet of flower monsters, sold at Horrods. They are among the higher leveled items, starting at level 26. Petal Pals are a range from Jellycat, which were released in 2008 - the in-game collection is likely hinting at it, but parodying it through taking the name literal, making the actual collection different type of flowers.
