TWICE's New Character 'TDOONGZ'

In the Korean comments

The comments turn the reveal into a guessing game: one reads, in translation, “It’s surprisingly fun matching each character with its owner.” Another supplies a nine-animal checklist: rabbit, dog, raccoon, squirrel, unicorn, penguin, cat, tiger and deer. There is also concern for TWICE’s earlier Lovelys characters; one commenter asks, in translation, “Lovely isn’t going away, right?”

What the words mean

“쥔장” (jwinjang, owner) is a playful, casual form of “주인장” (juinjang, owner). In the comment about matching each character with its “owner,” it means identifying the TWICE member represented by or paired with that character, not a literal pet owner.
