Sunrise Spring: Bluto in Seashell Shore
Midday Gardens: Sleepyhead in Spooky Swamp
Evening Lake: The chinese style dragons in Fireworks Factory, I named them Neo(red one) and Geo(purple one)

The qualifications for being a miniboss? They must be something that you have to fight(duh), have a health bar, and be fought by Spyro. So the yeti in the boxing challenge doesnt count.

It's interesting that Neo and Geo are the only minibosses that arent rhynocs, isn't it? Also, Midnight Mountains doesnt have a different miniboss probably because of the Bonus World. The Sorceress is both bosses.

What do you think?
