Meet Lava Champ: This tough lava lamp dog toy is anything but mellow, man. Lava Champ has so many groovy features, your pup's mind will be blown: the toy is a slow-feeder treat puzzle (whaa?!), so you can, like, drop treats or kibble inside the center, give it a toss, and watch your dog fight for their munchies—and the wacky bounce makes for even more unpredictable movement. The exterior is made of durable, glow-in-the-dark rubber too, which should match perfectly with blacklight posters. For an even more rewarding playtime, spread peanut butter on top and watch your dog chow down. Oh and dude—it's also dishwasher safe for the top rack and BPA free. Pretty radical, right? Made for medium and large dogs.
