Just a tip. Just before we discarded an old vacuum hose I cut of a part and it turns out to be a great toy for tugging and running around with each other. It's a long hose so plenty of replacement toys
I used to make toys out of old ripped socks. Just need to find a long one with no holes and stuff it with old socks instead of throwing them away, when it’s full, make a knot on the top and if will last for a few tug games etc.
