I have so many different answers I could give because I pretty much exclusively watch cartoons/animated shows whenever I watch traditional TV content instead of videos online.

Though I'm going to say that right now it's definitely Summer Camp Island, created by Julia Potts for Cartoon Network. Can't remember whether Max removed it ( most likely, so enjoy finding it on the high seas if it was ), but it's a 6 season show about an 11 year old anthro elephant kid, Oscar, who goes to this summer camp on an island with his best friend, an anthro hedgehog named Hedgehog for what ever reason. She's literally the only character named like that and it's never explained in the show why. Also, the island is magical and 3 witch camp counselors run it.

The early seasons like season 1 and 2 ( possibly others but I can't remember off the top of my head ) can be watched in just about any order, but there are a couple episodes here and there that will fill you in a little more on a slowly advancing plot in one way or another. Other than that, at some point they start getting more into a storyline that ends up having an amazing end ( even if season 6 feels a little rushed and has some loose ends that aren't neatly wrapped up ).

It was originally just 20 episodes that CN decided in 2018 to do a full 48 hour marathon on Boomerang ( which I assume was just to kill it because it's something new that could have been spent towards their existing stale lineup ). I'm pretty sure most fans were genuinely shocked and surprised when more episodes were announced. I know I was. Either way, I'd personally recommend it.
