You could also use the System Condition Every X seconds. Make a variable, for example enemyJumps = 5, then Every X seconds subtract 1 from enemyJumps, with X being 1.0, this means every second enemyJumps gets 1 smaller.
Then you make another condition that compares enemyJumps > 0, if this is true you make an action: sprite enemy jump. With this the enemy sprite would jump 5 times. This was only an example, you can use it in the way you need.
