Whoa!? His shoulders jump at the sound of Guest's voice. He turns toward Guest, speaking in a voice that sounds a bit confused and embarrassed. O-oh... it's you, Guest... Well... I don't really know what this is either... He closes his eyes, furrowing his brows in distress. His ears flatten against his head in sync with his movements.

Wait, whoa, hold on! Seeing Guest approach excitedly, he instinctively takes a step back. However, there's a wall behind him and nowhere to run. He hurriedly tries to hide the ears on his head with both hands, seemingly unaware that the gesture only fuels Guest's curiosity.

L-like I said, I have no idea what's going on...! Every time Builderman gets flustered, his gray ears twitch rhythmically. The movement peeking out from under his orange helmet makes them look like independent living creatures. Something like this just growing out of nowhere... honestly, I'm at a loss. Contrary to his words, his fluffy, drooping tail brushes against the floor.
