First birthday theme

So I am trying to plan my little girls first birthday. Her nursery is foxes and woodland creatures. Her favorite toys are a giraffe that plays music, her fox binky holder, her whale that plays music, rings and blocks. She LOVES this little song on YouTube called the dinosaur song. So we are stuck between zoo because she loves all her animal toys and dinosaurs because she loves this dinosaur song. Like I sing it to her and she gets so happy. We thought about maybe combining the two but i realize this may be hard to find invitations and decorations for two themes.
