That is so funny and cute! Reminds me of my Roscoe and his tennis balls. No matter how many were in the house (sometimes 7 or 8), he'd round them up and stand guard over them...they were all his! Poor Cassie rarely got to play with toys because Roscoe always thought they were all his.
Funny thing is, Duke is exactly the same way! He always tries to take the toys from Violet and then they end up playing tug-of-war with them (and she often wins!). Last night, they were actually fighting over who go the rock I brought back from Yosemite. Silly beagles, it's a rock!
You can almost see by the look on Luigi's face what's going through his mine, Go ahead and try to take one, I dare ya! LOL He is such a pretty boy, even when he is being a toy hog.
