"Ribbit ribbitribbit RIBBIT!" That's frog for, "I think you should buy this really super cool clear backpack!" "Ribbit ribbit" is frog for "I appreciate your advice and value your opinion as a trusted friend!" "RIBBIT ribbitribbit" is frog for "Can you also pass me some corn chips while you're up", which is less relevant to the current conversation, but still interesting to know!
