Houston's Aquarium and Interactive Zoo (Humble, TX)
Located here: 5440 N Sam Houston Pkwy E, Humble, TX 77396
Took the kids to this small zoo that was actually pretty fun. You can interact with almost all the animals there, much cooler than the real Zoo downtown. Kids got to feed the fish, stingrays, sharks, you can also feed some birds and even a giraffe. There's a nice play area indoors with bouncy houses if it gets too hot outside.
