If you use a Mushroom/Golden Mushroom, you can roll 2/3 dice blocks. If you get doubles (two of the same number) out of a Mushroom, Toad will give you a 10 coins present. If you get two 7s, Toad will give you a 20 coin present.

Using a Golden Mushroom is better too. If you role triples (three of the same number), Toad will give you a 20 coin present. If you get triple 7s, Toad will give you a 50 coin present! Very difficult to pull off.
