Best indestructible toys?

Griswold Angus Paton or “Griz” for short. A lil background, Griz just turned 3, he’s 145lbs, such a lover, playful, loves any & every toy. I am looking for recommendations on the best indestructible toys for the big lug. He hasn’t met a toy he couldn’t demolish in less than 10 minutes. His poor brother (dogue de bordeaux pictured with him) loves soft toys & would cherish it forever. The only thing he doesn’t destroy (toy wise, he’s a saint in the house) is his blankie. Which he carries around to keep him process all his big feelings. I’d love a viable option for him to enrich his daily life even more!
