Writing ink is generally not toxic, and must be consumed in large quantities before medical attention is needed. The amount of ink contained in a pen is unlikely to cause toxicity in Pancho, but I would be more concerned if he ate the pen portion itself. If he hasn't, gently flush out his mouth with warm water, and clean any ink in his mouth. You can monitor him for signs of ink toxicity (vomiting, diarrhea, lethargy, mouth irritation), and if you see any of those signs, take him into the vet right away. Otherwise, I think he will be ok :-)
