Noisy Squeezy Hippo
This Chew Friendly (not designed for chewers, but not likely to burst has it has no filling and has a hard exterior) Hippo is larger than many of our sensory items, if you squeeze it, it makes a noise (not firghtening for most). You can control the level of sound it makes by your strength of squeeze. It is a great cause and effect item which can be used by the individual or carer to help create imaginative play etc. It is also great for Hippo and/or animal lovers and can be used for display too for those who like to look. 
 
Please note: If the white tube that makes the sound comes out or breaks, it could pose as a choking hazard. Adult supervision is strongly recommended.
