Bounce-Back Action: These baby toys use a special clip base that lets them sit upright; when your infant presses them down during tummy time, they satisfyingly spring right back up for more fun * Promotes Neck Movement: The engaging pop-up motion of these sensory toys is designed to encourage up-and-down head lifting and side-to-side neck turning, helping to strengthen crucial muscles * Three Ocean Characters: This set includes a friendly whale with a crinkle texture and mirror, a seal with crinkle fins and tabs, and a squid with crinkle fins and tentacles, all educational toys * Multi-Sensory Details: With multi-textured fabrics, sounds, and other tactile elements like fins and tabs, these are also a suitable baby teething toy and learning toy for curious babies to explore * Linkable for Travel: Connect the whale, seal, and squid together vertically or horizontally to create a chain of stroller toys for on-the-go entertainment; a thoughtful baby shower gift for new parents
