Baby boys first birthday!

My LO is going the be the big 1 year old in January. I’m losing my mind trying to find a cake that will work for his birthday. Back story is my baby shower theme was snoopy and Woodstock and his nursery is snoopy and Woodstock theme. We are thinking about doing an outdoorsy theme for his first birthday. Any ideas on cakes and a smash cake that I could do for him that’s age appropriate but still goes with the decorations and theme we are using for his birthday.
