Cthu-goo-ga-ga! Introduce your great young one to the mysteries of the Great Old Ones with the Sippy Cup of Cthulhu, the most eldritch of all baby gear.
Our totally spillproof, BPA-free, 360-degree sippy-vessel seals automatically, much like the portals to non-Euclidean dimensions beyond the stars, after one drinks from it. Four out of five dentists recommend it for human children (6 months and up) and unholy star-spawned hybrids (one thousand aeons and up) alike. The patented design keeps teeth in tip-top shape for tearing and rending, and the EZ-grip handles are perfect for tiny hands and/or tentacles.
After all, why should the grownups have all the fun/terror/cosmic dread?
