I have always wanted to go to see Puxatony Phil.  I am trying to instill this love of Groundhog's Day into Ivy.  Our library only had one book - Iris Hiskey Arno's and Renee Graef's The Secret Of The First One Up.  I wouldn't call it a "favorite" of Ivy's but she is interested in the groundhog's shadow.  Little Lila's Uncle Wilbur tells her that there is a special secret for the first groundhog who wakes up after winter hibernation.  Will Lila be the first one up?
