DerekHandley suggested Groot and Poison Ivy. I had tackled the same subject the previous year in a more cartoon-y style which I really didn't like (it's on here somewhere) so I really wanted to do a version I was happy with. I'm happier with this. I suspect most people will assume that Groot is under Poison Ivy's chemically induced spell, but no - they are just really pleased they found each other.  Hey, it's Valentine's Day!
