Eric is going on vacation to Florida, and he's taking some of his friends with him. However, he has obsessive compulsive disorder, and he has some very strange requirements on what his guests must bring.

For instance, his friend Jon can only come if he brings something like orange juice. Stacy can only come if she takes bags of peanut M&M's and such. Billy could go if he takes denim jeans, but he must also bring bananas. However, Eric's friend Janet couldn't go on vacation with him no matter what she brings.

Eric's friend Russel could go with him if he brings ketchup. If Elvis were alive, though, he couldn't go with Eric.

Eric's friend Ashley has the same requirements Stacy has, and so does his other friend, Yao. However, Yao has an additional requirement: He must also bring ripe pumpkins, which Stacy and Ashley need not bring.

Eric's friend Paul could go if he brings plums, and Garry could go if he brings some $20 bills, but he must also bring tomatoes and a yellow smiley face. Eric himself is only able to go on vacation because he is bringing his wife, who had just returned from Florida.

So the question is: Can Robby go on vacation? If he can't, why not? If he can, what must he bring?

I apologize for making a mistake and forgetting Garry's third item, but your solution does meet all the requirements from the information supplied.

It almost sounds like you are accusing me of being mad that you solved the problem, and so I changed the solution and added a requirement.  I hope this isn't the case, because I didn't just add the yellow smiley face for fun, I accidently forgot it in the original problem.

Your solution does account for all the information, but it is a little obscure.  While you may say that letters of colors are obscure, I don't think so, because it is one simple unifying theme.

Again, I apologize for my mistake.
