Uniquety

I have one of these beds. I really like it a lot. We bought it for Zizza when she graduated the crib.
But here’s the problem. We moved her into the guest room where she now sleeps in what was the guest bed. It’s time for Enzo to move it on up from the crib but the minnen bed is just so darned girly!
When we bought the bed we thought it would stay with Zizza, so we didn’t consider it’s girlyness a negative. Things didn’t pan out that way though, so a negative it has become.
Help me folks, what can I do to boy this thing up? I thought of completely slip-covering it but honestly, that’s plain too much work.
Will putting boy bedding on it work or will it just look like boy bedding on a girl bed?
