D2 is a very helpful toddler, in case you did not know. I bought him a $4 "gardening" set at Kmart that has the shovel, rake, and tiller thing.
He was so in awe of finally having a "BOSYAAAAA!" (big) shovel), but he's having fun with the rake, too. (The tiller thing he's not sure what to do with yet, and uses it as pretend vacuum cleaner, because, duuuude, vacuum cleaners are the best!).
