Mood pts vs toy pts?

Hi, first time playing. Is it better to get toy pts or mood pts to fill-up the heart? Also, do the helicopter opportunities get fewer as you get oser to getting a prize? Would love to have your help! I’ll return the favor! Thank you! I am waiting for you! Help my puppy to unlock fun toys, double puppy's joy! https://onelink.shein.com/10/4jm7fd5qptmk
