Collecting Yamcha's Turtle Stones may seem like a waste of time, unnecessary, and stupid. The truth is, it is a quick way to make TP Medals in almost no time at all. There are a total of 25 Turtle Stones to be collected each time Yamcha summons you, and you only need to collect 2 - 9 stones to make your TP medals each time. Unlike Krillin's "Milk Deliveries," it only takes maybe 2 - 3 minutes tops to collect the bare minimum amount, and if you take the time to collect all 25, you receive 25 TP Medals.
