I don’t think it’s okay. Wouldn’t old school Catholics call this a “distraction” talking about toys at Adoration? I don’t think it’s very respectful to call Jesus your “friend.” Would you think it’s fun to take out the Host of the monstrance and let Jesus ride in your toy fire truck? See what the other Adorers say.
Jesus is our God, our Savior. We owe Jesus our complete devotion and worship. Jesus is present in the host in the Monstrace. In His presence we should be on our knees worshiping Him. In fact we should be laying prostrate out of respect.
At Adoration I like to break up the hour into Adoration, Contrition, Thanksgiving, and Supplication. I try to focus my mind on the topic and try to avoid letting my mind wander.
