Stella is, as one YouTube commenter points out, "all kinds of awesome". After all, could you point out three key faults with a toy triceratops at the age of four? Us neither.
Uploaded by her mum Sarah under on her "SarahHattonArtist" YouTube channel, it shows Stella with her dad looking at some toys at a store - some anatomically inaccurate toys, no less.
Succinctly explaining just why this plastic dino just doesn't cut it, it's enough to make you involuntary "Nawwww!" out loud.
Seriously, someone get this girl a David Attenborough-style TV show, and quick about it. We all have things to learn from this little lady, especially in the dinosaur horns department.
In the YouTube video's description, Sarah says: "I think I'll renew my museum membership..." That sounds like a brilliant idea to us. Plus, let us know when she's doing tours, will you? Cheers Sarah.
