Think about it

then again maybe they grow when they get older.

I was thinking more like they were cousins or smth

I once read that Monster Kid might be related to Alphys somehow and the reason that Monster Kid idolizes Undyne is because Alphys talks about her a lot

That makes sense

Both dinosaurs, both yellow, both have those teeth, does that mean...

I actually saw the two of them as cousins

Ngl me too

I like it. They're related somehow...
