Filled one with water and handed it to my nephew during his bath—he hasn't stopped giggling at the little tweet sound. The tail is easy for small hands to blow on, and it’s held up fine after a few splashes.

The kids were cracking up the moment we filled these with water and blew—the little chirp is surprisingly realistic for something under ten bucks. Bath time has turned into a mini bird concert, and they're sturdy enough to survive being tossed around the tub.

The pitch is a bit tricky to get exactly right, but once you fill it just enough, the sound is surprisingly charming. My toddler gets a kick out of making the little bird "tweet" during bath time. Good value for a fun, simple toy under ten bucks.
