Cricket displays his "Bucket list" in this episode, which is a list of things he's always wanted to do with a bucket. In real life, a bucket list is a list of things you want to do before you "kick the bucket" hence Tilly's line about preparing for death.
This is the first appearance of Tilly's potato sack pal Saxon.
Moral for Backflip Bill: Cricket learned not to put too much pressure on someone and let them have fun.
Moral for Cricketsitter: Tilly learned being responsible is hard work.
