It is a game that you play if you want to relax. I definitely would like to relax with it. It also reminds me of Yoshi's Island, but without baby Mario. It seems interesting.
Yoshi was one of my favorite cartoon and in-game characters as a kid. Maybe I am showing my age now but I used to get up at 6am everyday to watch it on TV. Check out the intro here
I was mortified when the show stopped after one season. It was the only one really shown here in the UK so I had to make do with Sonic after that I'm now re-watching it on YouTube, so great!
How much do Wii U's retail for these days, I do think it would be nice to pick one up.
