>>9435063Mermaids are like Princesses or Fairies in the doll toy business. It's a common trope used in many doll lines to broadly appeal to little girls.
If that wasn't the case, then Mermaze & Mermaid High would be considered rip-offs of the numerous Barbie mermaid sub-lines, which in itself could be a rip-off of "The Little Mermaid."
There's also the fact that Mermaid High is new, yet so far hasn't made much of an impression on kids or collectors. Not like Bratz or Monster High or OMG when those hit the scene. You're trying to spark a controversy that just isn't there.
