Sammy's Adventures follows a sea turtle called Sammy and his friends
In 1959, Sammy, a Green sea turtle, hatches on a deserted beach and while trying to climb up a sand slope is caught by a seagull. He manages to escape along with another hatchling sea turtle named Shelly who was caught by another seagull. Sammy falls onto an old raft and gets carried into the open ocean, losing Shelly. Later he befriends a leatherback hatchling named Ray. The two friends grow up together.
Sammy and Ray are supervising their new grandchildren, when seagulls attack them and both Sammy and Ray and two of their grandchildren Ella and Ricky are captured on trawler. While Ella and Ricky are separated and sent to the seabed, Sammy and Ray are taken to an aquarium with Lulu, a lobster with dissociative identity disorder and Jimbo a bug-eyed blobfish. Escape plans are run and tried by the leading seahorse Big D. Ella and Ricky set out with Annabel and Margaret, the pink octopus mother and daughter in order to rescue their grandfathers, getting chased by a pair of barracudas when they get there. After much communication trouble, Ella and Ricky interpret from Sammy that in order to escape the aquarium several squids expel ink into the ventilation system, while all the aquarium inhabitants play dead. Before initiating the escape plan, Sammy and Ray get the tyrannical Big D out of the way. The reluctant aquarium manager opens the emergency doors allowing all sea creatures out to freedom.
Ella et Ricky sont deux jeunes « enfants » tortues qui vivent dans un récif coralien, organisé comme un village, en compagnie de nombreuses autres espèces sous-marines. Ella et Ricky ne rêvent que d’une chose : vivre l’aventure du grand large ! Rien de plus normal : pour les jeunes tortues marines, parcourir les mers sans s’arrêter dès la naissance est une chose naturelle, inscrite en elles : c’est ce qu’elles appellent le « voyage ».
