Strategy guide
- 1.Focus on the air pump tool - drag it directly onto Jenny's left biceps first to inflate her muscle;
- 2.After inflating one biceps, immediately drag the air pump to her right biceps to complete the muscle growth;
- 3.Watch for visual feedback - inflated biceps will visibly grow, indicating you're on the right track.
Common mistakes
- 1.Trying to tap or swipe the weight directly instead of using the air pump on Jenny's biceps;
- 2.Using the air pump on only one biceps instead of both to make her strong enough;
- 3.Dragging other objects like the dumbbell or bench onto Jenny instead of the air pump.
