Flight of the Bumblebuns.

This video has music, so be careful if you're viewing it at work!
Simon and River discover a new favorite toy.
(Noticed an ad showing up a couple of seconds in and I don't have a monetized YouTube channel or blog, so sorry about that--you'll just have to close the ad when it pops up because I don't have control over it.)

Best toy ever!

I bought the bunnies a wiffle ball and used a tiny funnel to put oats inside of it turning it into a bunny kong treat toy.
This would also probably work if you have a bunny that eats their pellets too quickly--they'd get a bit of exercise and would only get some pellets at a time.
Bonus video of them playing with their new toy:

Purple towel peek-a-boo!

I had to take a still because what Simon did was just too cute not to.

I think that the purple towel will remain the coolest toy ever due to its versatility in Simon and River's adventures.
