I smashed a Whirlm one day and guess what Two baby Whirlm came out! I guess this is how it goes: Find a pinata thats easy to get(Whirlm's a good choice) and keep getting new residents of it. Look at the name and see if it's the 99th(It would say: Whirlm99 unless you nicknamed it. If it is, smash it! If it dosent work, and it gets ill, that means it was too young(even if its not a baby anymore). wait for a few more days(game's time) then try again. If it worked, youll hear a real baby's cry. Sell one and smash the other for easy cash. Now try it on something harder: Tigermisu, Swanana, Galagoogoo, etc.
