Aack... Ack ack... Ack ack ack! ATLOK has a more somber tone than ATLA. That sort of animation is a better fit in a fun action-adventure than it is in an action-drama.
It's from the Book 3 ATLA finale where Suki and Katara go off looking for Aang on Ember Island only to encounter Actress Aang and Actor Toph doing a street performance.
Ack! Ack ack ack-ack ack! >>117914 heh be neat if we got some wall exaggerated animation in the beginning episodes of book four and Varrick is making a Korra mover and Korra is the technical advisor.
