TOMY Do-Re-Mi Dolphins will bring a smile to your little ones and have bath time ringing with hundreds of home-made tunes! Link the rings together in a circle and play a matching game, dropping each dolphin into its coloured ring. Then tap each dolphin to hear a different note! Rearrange the dolphins in different sequences and play your own songs over and over! Play with the dolphins in a circle or in a line, or let them float on their own for hours of interactive fun! No batteries required. Suitable for ages 12 months and over.
