I think Mortimer should have a response for Frogatto trying to bring him a non-golden ant. I’m thinking something to the tune of:
Mortimer: Thank you, but I already have one of those.  I wanted a golden ant.
Frogatto: This isn’t a golden ant?
Mortimer: No, it’s not golden.
Frogatto: I don’t follow.
Mortimer: Golden ants are yellow.
Frogatto: Yellow?
Mortimer: Oh… oh.  I’m so sorry.  I assumed you knew what yellow was.  I always make that mistake.  I’m a scientist, you see, so sometimes I forget to simplify things for those outside of my profession.
Frogatto: What is this… yellow?
Mortimer: Yellow is a color.  You know, like red or blue.
Frogatto: I know BOTH of those!!!
Mortimer: Yellow falls on the color wheel between green and orange.  In the spectrum of visible light, yellow occurs in the wavelengths between 570 and 590 Nanometers.
Frogatto: Oh, you mean like a lemon?
Mortimer: Yes!  Like a lemon.  Wait, how did you-
Frogatto: Okay!  I’ll go get you a lemon ant!
Mortimer: Golden ant.
Frogatto: Oh, right.
