Venting: The constant "I'm bored" when there's literally toys everywhere

Summer vacation and my 6yo says he's bored approximately 47 times per day. Meanwhile our living room looks like Toys R Us exploded. I offered him like 10 activities and he rejected all of them. I'm not trying to be entertainment 24/7. Am I being unreasonable expecting a 6yo to play independently for like... 20 mins? Feels like I'm doing something wrong
