Nickelodeon Cruise ship

After five years of SpongeBob SquarePants, Dora the Explorer and slime at sea, the agreement between Norwegian Cruise Line and Nickelodeon is coming to an end.

The Miami-based cruise line said in a statement that Nick-themed entertainment experiences will not appear at all on Norwegian Escape and will end on Norwegian Epic by October. On the other four ships that feature Nickelodeon activities — Getaway, Breakaway, Jewel and Gem — the themed entertainment will be available until Jan. 3, 2016.

“We thank Nickelodeon for being a great partner and helping us to provide family entertainment on board our newest vessels, ” the cruise line said in the statement.

Norwegian said that it would “continue to raise the bar on family entertainment at sea” and highlighted new offerings on the upcoming Norwegian Escape, including a new nursery for kids between six months and three years of age and a bigger sports deck.
