last toad in 2-1

Well I don't know which two you found so I'll go through all three. 1. On the first screen all the way at the top left, there is an upside down pipe, go through it and there's a toad. 2. On the second screen, you come up through the pipe and go to the right. Go down the first short pipe, collect your coins and go down the pipe at the end of that screen, you will come up through the pipe below the one you originally went in and there's a toad. 3. One the third screen as soon as you come up the pipe, I'm pretty sure there's a toad there too. Hope this helps.
