This is a 16x16 horizontally moving sprite, which will try to follow Mario and periodically drop coins and play a sound effect. After dropping a configurable amount of coins, it will disappear in a puff of smoke.
If the extra bit is set, it will successively toss a list of sprites and then disappear. The sound effect for each sprite can be customized.
No GFX included, so you will have to draw them by yourself.
