A bunch of half bean- half dogs from Japan, so you you know it's messed up. They are complete trolls, messing with people at every turn.

Boy: *Studying hard*
Mame-Shiba: Did you know an ostrich forgets what it just learned very quickly?
Boy: NO DISTRACTIONS!

Man: *About to kiss girlfriend*
Shiba: 42 million germs per second are transmitted while kissing!
Man: Never mind.
