Jackson's Xmas List to Santa

I helped Jackson write his Christmas list to Santa last night and then he put it in the mailbox this morning. The first half of this list was totally unprompted and I have no idea what he means for some of these things. Animal cards? What are animal cards? A lion? Anyway, the second half of the list (starting with "cars")is what came out of his mouth after asking him what kind of toys he wanted; afterall, #2 on his list ("toys") is pretty vague. And yes, he said "train on a train track". Apparently, just any old train would not be good enough - it needs to be on train track.
