Sharky is a soft toy baby shark who lives with the host of a children’s blog. One day, thanks to 3D animation, the toy comes to life and enters an amazing underwater world. There, Sharky becomes a student at a school located on the ocean floor. In class, he meets a starfish, a stingray, and a butterflyfish. Their teacher is an old octopus who explains not only school subjects, but also simple truths: why it is important to share, help others, and not be afraid to ask for help. Between lessons, Sharky and his new friends set out to rescue those in trouble.
