Attack of the Lobsters

Today, RoRo was able to tell us about one of his bad dreams for the first time. He woke up from a nap crying inconsolably. We soothed him back to sleep, and when his nap was finished we asked him what happened.
"Did you have a bad dream?"
"Yeah!"
"What did you dream about."
"Oh, a yobta!" [translation: a lobster]
"A lobster?!? What was that lobster doing?"
"Get you RoRo!" [translation: it was chasing him, saying 'I'm going to get you, RoRo.']
Daddy told RoRo that the next time he dreamed about that lobster, he would come stomp on it, and our two dogs would also eat it up, so it couldn't hurt him anymore.
RoRo was so tickled by this that all evening he's been yelling, "Dada tomp-tomp yobta! Card EAT yobta! Molly eat, too!"

(RoRo always likes to see the lobsters in the tank at the grocery store. Usually he watches them swim and crawl around for a while, we talk about their claws and tails and things, and then he says "Bye-bye yobta! Have fun!" But the other day we saw a really huge lobster that was chasing the smaller lobsters around the tank. Not only was this lobster about the size of a small cat, it had one claw that was really overgrown and was itself about as big as another lobster. Ro was scared of it, and it must have been this Monster Yobta that inspired the nightmare.)
