My first rod and my brother’s was a snoopy rod. My little brother had a son of his own. He got what appeared to be the same rod combo we had but graphics were the Pixar Cars movie. The nephew loves it!
He turned 6 this year and came to Minnesota for the first time. He got another spincast combo at the cabin but full size(cheapest grandpa could find). He did “okay” with the larger rod but look out when it was time to cast.
Walmart, Kmart, anywhere that has this classic spincast combo. I know you wanted to stay away from Snoopy but it does fit the bill. Besides it’s harder to break and cheap to replace when it does get smashed.
