If you are reading this article, you probably already have a toddler in your life that LOVES CoComelon. The expression on that child's face and the collective joy a CoComelon Birthday Party will bring to the group will be worth it. If you want a more practical reason to pick this theme over another, I'm happy to oblige. CoComelon is wildly popular, so you should have no problem finding CoComelon supplies, and everyone attending the party will understand the theme (and likely equally excited about it). A bonus is that most bakers (including those at the grocery store) can help you find the perfect cake for the theme.
