The objective of the toy level is to collect the required amount of toys. That amount does not have to be the exact number of all the toys on the level. Moreover, it's usually so. For example, level 24 requires you to collect 30 toys to pass the level, whereas there's a total of 40 toys on the level. However, the amount of required and total toys can also be the same, which makes a level more difficult (example: level 64)
Toys can be ducks, submarines and octopuses. There's no difference between them.
