Netflix continues to ramp up its post-SpongeBob/Dora kids offerings. A week after sealing a huge deal with DreamWorks Animation for original content, the subscription service has inked an exclusive distribution pact for Mako Mermaids — a spinoff of the Australian teen drama H20: Just Add Water, which is a worldwide hit in syndication and is available on Netflix. All 26 half-hour episodes of Mermaids, from Jonathan M. Shiff Prods., will premiere July 26 in the US and the streaming service’s other territories. The series centers on teenage Zac, who is camping on Mako Island and is secretly watched by three young mermaids tasked with guarding the isle. After an encounter with magical water, he becomes a fish-tailed merman, causing problems for the mermaids. The news comes less than a month after the expiration of Netflix’s content deal with Viacom — whose programming now streams exclusively on Amazon’s service — and six weeks after it pacted with Disney for the kids series Jake and the Never Land Pirates and Tron: Uprising.
