i ALSO think leebit would say "ha!" and i definitely feel he would also do all of minho's weird little gibberish noises and "hehe" laughs!! jiniret i feel would make cute confused noises... actually lemme just make a list:

• wolf chan: "ohh" (like an interested noise, he is a good listener")
• leebit: gibberish, "ha!" "hehe!" "heheh"
• dwaekki: "UH!" à la binnie (also "nyeh!")
• jiniret: "huh?"
• han quokka: "whoah!" (surprised noise) and also pouty whines
• bbokari: "heheheh" (gremlin cackle) but also "whee"
• puppym: dead silence. that's how he hunts you
• foxi.ny: "hmm" (judging)
