The Rainbow Lure is a type of lure in Nintendogs + Cats and is only unlocked once in higher levels of Lure Coursing competitions. This lure is ( like any other lure ) used to practice in the Nintendogs + Cats gym and to do Lure Coursing competitions. It is in the shape of a flower and features the colours of the rainbow on the petals. It makes the same noise as the Pro Lure. It is the fastest lure in the game, however it can be notoriously difficult to control, especially if your puppy's speed is slow. It must be unlocked with 6,200 Owner Points and can be obtained at Mr. Recycle.
