Mmmm, this probably isn’t how it works but couldn’t he hire a sculptor to make the golem smaller? Atleast make her curves bodacious... unless it’s a guy though they could still have bodacious curves in the chest area i suppose.
Dunno if someone already said it but the untranslated sfx ("カチャ/kacha" i think) may be the skeletons moving so the translation may be "click, clack" or something that bones hitting sounds like.
