This hippo teether is soft and comforting, the perfect little friend for baby during teething. The two textured teethers are excellent at soothing baby's sore gums. The crinkle paper arms and soft plush body provide tactile stimulation, and the lightweight design makes this hippo easy for baby to hold and play with. Press the light up heart button to hear the hippo sing, speak and play music. Remove the plastic core, which contains all electronics, to surface wash the hippo and keep it fresh and clean.
