Nice work. :]

Since you asked for feedback/corrections:

1)Serpents don't get frozen on any map apart from the ones that spawn as Rendtail's mobs, from the eggs.
2)Spiders exist only in the fourth map, not the last two maps.
3)Spitfire eggs do drop, kinda like Archons, both I've seen were from the Komodo mobs. It appears like a golden chest and not an egg though.
4)On caves, the mid-park rock description has a typo, it's five serpents not shamans.
5)There are two types of spear/bow tribalmen: masked ones and unmasked ones. The second have more HP/DMG/ARM.
