Those two must interact
The moment I saw Litmus Cookie and her story, I felt that she’s really similar to Strawberry Crepe Cookie except for being slightly lazy.
They both have “cybernetic powers” (I think what those glowy technology that appears around them) or Magichanical powers.
They both love to collect samples and analyze anything they find interesting!
They both love robotics: Wafflebots for Strawberry Crepe and Litmungus for Litmus Cookie.
Another thing I find cool, is that the Yogurt Phantom costume for Crepe have two ghostly cats with their own facial expressions, are like the same for those two bubbles around Litmus Cookie! (I just wish Yogurt Phantom was canon)
Not having those two interact would be a CRIME! I need to see them analyze stuff together or act like two nerd maniacs!
