A really, really tall pet wolf. [He's seen stranger, so he's not too sure he can judge Wolf's height, but it definitely catches him off-guard.
Hearing Sphere's name, though? That gets him to bury his head in his hands.] Grife, Kon! All these years, he makes fun of me for stuff and it turns out that he can't name anything! I don't mind him naming things, but... even "Josie" or "Tron" would've been better than freaking "Sphere."
