Deerling is exceptionally energetic and exceptionally clumsy. It puts 110% into everything it does, which usually results in 110% crashes, spills, and other such mishaps as it goes about casually wreaking havoc. It never seems to be very put out by the accidents it causes, because it is certain that the important thing is that it tries.

Zigzagoon is extremely good at ferreting out hidden things and spends most of its time nosing around where it probably shouldn't be. Stealthy and difficult to keep pinned down, it has a habit of reappearing at Junko's side with potentially valuable items. It seems to like giving her presents and doesn't mind so much about where it obtains these presents.
