I'm not sure what you mean by secret sprites, but here's a list of all of them and how to get each one: http://www.fogu.com/hm6/chan3/sprites/index.php
If you mean the little red, blue, and yellow sprites they're names are Arthur, Billy, and Carlos
Sprites can be categorized into several types, including static sprites, which are fixed images or animations that do not change, and animated sprites, which consist of multiple frames that create motion when displayed in sequence. There are also 2D sprites, often used in platformers and side-scrolling games, and 3D sprites, which are typically used in 3D environments to represent objects or effects. Additionally, sprites can be classified based on their role in gameplay, such as character sprites, enemy sprites, or environmental sprites.
Sprites are graphics that are ripped from video games, mostly from older such. These sprites can be used for comics, animation or games. Sprites usually come in a big sheet of sprites with a background color like green or blue, to make it easy to separate the sprites from the background. Sonic sprites are sprites that are ripped from a Sonic the Hedgehog game. You can see Sonic sprites in action in flash animation on the net, for example in the Super Mario Bros Z series on Newgrounds.com.
Sprites are not real.

Sprites - although they aren't technically fairies. Fairies are sprites but not all sprites are fairies.
You could always take one sprite from the sheet of sprites.

Since the Pikmin games do not use sprites, they are none to be found. There may be unofficial custom sprites, though.
