You got one more choice of what to catch in Mt. Moon!
Shovel is the Sandshrew's name. Bubblegum has yet to be caught yet.
Someone other than Clover get's to choose the fossil.
EDIT:: Shows how much I know. According to: http://serebii.net/pokearth/kanto/1st/route3.shtml, you cannot catch a JigglyPuff on Route 3 in Yellow Version. ):
