Dinosaur Story by a little Dr. Suess

Sempi and I are at the swap n' play (an indoor play area). He's playing with a crane toy and I'm sitting on a chair staring at my phone. 

He deicides to rescue me from my boredom and brings three dinosaur toys to me and says "Appa, here, play with me".

So I join him at the table with three dinosaurs. Here's the ensuing conversation: 

Me: Here's a Triceratops, it says, "Woof, Woof". 

Sempi: ???

Me: Here's a Stegosaurs, "Oink, Oink". 

Sempi: *intent stare*

Me: Here's a Brontosaurus, "Mooo, Mooo"

Sempi: No appa, this one says "Grooo", this one says "Bloooo" and this one says "Octopus Stew".
