Simba Rafiki Timon and Pumbaa are Silver Box characters, witch means they aren't hard to unlock (open enough Silver boxes and eventually you get them all 4)
if you have all SilverBox tlk chars fully leveled up, you get a group collection reward in the form of...Mufasa

Scar can be won only in rare villain events, wicth is sad.
Nala and Shenzi are the most difficult to get.
Who has them all? And what more TLK characters would u like to see in Disney emoji blitz?
I would like to see: Zazu, Kovu, Zira, Kion, Beshte, Bunga, Ono, and maybe Kiara ok.
