Create a whimsical birthday-themed illustration that portrays a twist on the traditional zoo setting. Instead of animals, humans of diverse descents and genders are playfully contained within enclosures painted in vibrant colors and decorated with festive elements. Animals of different species roam freely, delightfully observing the 'caged' humans. The landscape is dotted with party hats worn by both the free-roaming animals and the humans. Overhead, a cheerful banner flies high, inscribed with 'Happy Birthday' message amid a shower of multi-color balloons and streamers.

Generated with these themes: Reverse zoo.
