I am not sure the badges are correct. There's three for defeating lions (which are only in one area) and only 1 for defeating elephants (which are in 3 areas). None for zebras, None for rhinos, None for Gorillas. There also weren't any "Street" badges. In many of the worlds you get a badge after completing all the quests in the areas. I actually use those to make sure I have done everything. I have gone through all of Zafaria and made sure I didn't miss any side quests.
I have badges for completing each area in Krokotopia (and one for completing all of it), I have a badge for completing Pegus Place (but not the other street) in Wisteria, I have a badge for completing each area in Marleybone and some that were boss specific, I have badges for areas and bosses in Mooshu, and I have badges for areas and bosses in DragonSpyre.
