I need help with 4U clover pieces

[SumiMuraMo]

My tamagotchi is already an adult and I haven't been able to get any of the clover pieces... he's been an adult for more than 48 hours and I didn't manage to find any of the first three pieces while he was still a kid so I was wondering if that's why I didn't get the 4th piece automatically (he's 6 years old now). At one point he ate the pizza and made a big deal about it with lots of hearts and a little celebration so I thought the pizza must be the first clover puzzle piece but when I went and looked at the clover screen it was still completely empty. I could really use help as I don't want to get him married until I get all of the pieces (if possible).

Also I don't know if it's related but I accidentally failed to get him the bathing skill icon when he was still a kid, but he has all the other basic skills and school skills. Can I not get the clover pieces if I'm missing a basic skill piece? My tamagotchi is Kuromametchi.

Do you have a soccer ball? That's one of KuroMametchi's clover pieces. And the clover pieces actually resemble a Tamagotchi's favorites, except for the 48 hour one.
