A common theme in the "Mario" series' power-ups is the fact that many items give Mario a semi-animal appearance, sometimes related to the item itself, for example "Super Mario Bros. 3"s Frog Suit, which turns Mario into a frog, and ""s Power Carrot, which turns Mario into a rabbit. Other times the item may not be related to the power; for example, the Raccoon Leaf gives him raccoon ears, a tail, and the power of flight. Other power-ups are overall more useful; in "Super Mario World", the Cape allows Mario to fly and glide, and a balloon in a later game in the series allows similar effects. "New Super Mario Bros." introduced other types of Mushroom power-ups, such as the "Mega Mushroom", which causes Mario to grow to a screen-filling size and the "Mini Mushroom" that makes him shrink to a very small size.
