The game was due out on Wii U and 3DS this Friday, but Nintendo has now announced it's been pushed back due to the need to make some unspecified changes.
No new release date has been given, though IGN has reached out to Nintendo for more information.
The official announcement reads, "We are sorry to announce that Scribblenauts Unlimited, a game developed by Warner Bros. Interactive and 5th Cell and published by Nintendo of Europe for both Nintendo 3DS and Wii U, will be delayed in Europe.
"It has come to light that some changes need to be implemented within the game before we launch them across Europe. We are very sorry for any inconvenience this may cause and we hope to make further announcements on the European launch of these games very soon."
