A special 2nd birthday

Unfortunately We live a days drive from family and are new to this state so we are friendless right now 😭

I'm trying to put together a special 2nd birthday for my twins next month and really don't know what to do! We don't necessarily have to stay home or go out, I'm open to all ideas! We can't travel to far because of my husbands job. I'm looking for something a 2 y.o would love without going all out I guess! TIA

*sorry I guess I should say we live in TX and it's already 100° and UV is supppperrr bad. Sun screen helps but they both still turn red. I try to limit their outdoor time between 10am-7pm. Butttt we do have an amazing childs museum close by!!
