This comes in the form of Nickelodeon Kart Racers which based on the name sounds like another kart-style racing game. It is expected to feature characters from various Nickelodeon franchises, such as Hey Arnold, Rugrats, The Angry Beavers, SpongeBob SquarePants, and more.
As noted by Nintendo Life, a few months about THQ Nordic was reported to have plans to bring back various Nickelodeon games from the mid 2000s and introduce them to a new generation of gamers, so this listing on GameStop doesn’t really come as a surprise. The listing has since been removed which either indicates that it went up earlier than GameStop wanted, or it was made in error, so it’s really anyone’s guess.
Either way we’ll have to wait and see what THQ Nordic plans to announce, but with E3 2018 coming up in the next couple of weeks, hopefully we’ll have more details then.
