Doo, doo, doo, doo, doo doo keep drinks cool for longer with Baby Shark! This Insulated Straw Cup features a silicone straw spout that is textured to encourage your child to sip from the top portion of the straw. Great for families on the go, the silicone valve in this straw sippy cup helps prevent leaks so that drinks stay inside the cup and off of your own little Baby Shark. Kids will drop things, but the Drop Guard™ bumper helps prevent breakage. That's SHARKtastic! When the cup is empty, the design makes keeping it clean simple.
