 * Bio Miracle boss pig.png The giant pig is the most common boss throughout the game. He has a particularly large snout, and through this snout, he spits out enemies to attack you.  You can turn his attack into his undoing by inflating the enemies that he spits out and sending them flying right back at him.
 * Bio Miracle boss walrus.png You'll only encounter the walrus once, at the end of the ice world. At first, he doesn't appear too dangerous, walking constantly in one direction.  But after a while, the shoves himself forward on the ice with surprising speed.  Get out of his way because he's invulnerable to attack when he does this.

 * Bio Miracle boss snake.png The flame spitting snake is one of the few bosses who does not summon other enemies to attack for him. He is more than happy to fry Upa up with his own fire.  Despite not creating any enemies, enemies are sure to appear anyway, giving you an opportunity to cool this snake down.
 * Bio Miracle boss seahorse.png High atop one of the swimming stages, you will reach the den of a very large seahorse who will appear to defend her home. She will summon a group of smaller seahorses to attack you.  Naturally, you must turn the tables on her, and send inflated seahorses flying right back at her.

 * colspan="2" | Bio Miracle boss Zai.png Little is known about the demon with the goat-like appearance that has managed to escape imprisonment and captured all of the souls in Upa's kingdom. Legend has it that he likes to surround himself with smaller minions who share his appearance.  If Upa can get them to break away from following Zai, perhaps he can use them against Zai and restore peace to his kingdom once and for all.
