I need b-day "cake" ideas!

I need birthday "cake" ideas! Kendi turns 3 years old on June 5th (hard to believe!). When Bright turned three we did this very cute but SUPER easy sunflower cake. Just a chocolate cake with twinkies around it. I'd like to do something similar for Kendi's birthday. We're just having a very informal family party at my mom's house. I don't want to do anything that takes much time, but I want it to be a bit unusual. Kendi isn't really that into cake, so we're open to ideas that aren't actually cake.

My mom had the idea to "build your own ice cream sandwich sundaes." That might be fun! But I think I would want to "ice" them with whipped cream and re-freeze them pre-party. Then they will look prettier when everybody piles on the various toppings.

Here are a few ideas I found online today.

Popcorn cake! It's basically like a rice crispy treat, with candy and nuts mixed in. Kendi LOVES popcorn and nuts, and this would be super easy and different.

OR...

Sunflower cupcakes. Cute, right? An oreo on top of a cupcake, with yellow icing. We're not really icing fans, so I'm thinking maybe we could use some sort of yellow candy instead???

OR...

The classic "ice cream cone" cupcake! Kendi LOVES ice cream. The only thing is I think I would use whipped cream or actually ice cream at the top, because again, we aren't icing/frosting fans around here.

OR...I think the cupcakes on the left are super cute and would be easy to put together. Kendi LOVES suckers, and the flowers are appropriate for a June birthday. Just not sure where I'd find the green leaves??

OR...

What ideas do you have?! Help me out here!
