Given that strength was an issue for Zanoba (only later did they mention clumsiness), the immediate solution I thought of was to have him sculpt large, durable materials like giant statues instead of soft clay..
That was actually what I thought, too! I imagined how Zanoba would start creating giant sculptures, like larger than life-sized, of pervy posed women he "admires", lol.
"She's the only non-loli girl in the show, your honor!" will be my defense in court
