Quick question please, I'm hoping someone out there in the ether might know the answer.
I have written a short story in which the main character's daughter is said to imagine herself as 'Spongebob' which would make her sister 'Patrick' and him 'Squidworth'. For those in the know these are characters from Spongebob Squarepants. This is the only reference to the character names in the story.
Does anyone know if I can use these names in this manner without infringing Copyright or Trademark legislation? I have tried to look this up but I'm struggling to find a definitive answer. It is not essential to the story but it was a small detail in it that I liked.
