Strategy guide
- 1.First, tap and hold Mary's arm to raise it, then tap her to shoot at the slime;
- 2.After shooting, drag the green slime horizontally to stretch it into a bridge across the gap;
- 3.Ensure the stretched slime fully connects both platforms so characters can walk across safely.
Common mistakes
- 1.Tapping on Mary without raising her arm first, which does nothing;
- 2.Trying to drag the green slime directly without stretching it into a bridge shape;
- 3.Attempting to tap on the slime repeatedly instead of dragging it to connect both sides.
