Inspect the mirrored route before reshaping
Shape and orient the paper mirrors so the egg has a useful route toward its destination. Watch the repeated surfaces below your characters, not just the bodies you directly control.
The Mocking Birds layout shows several repeated paper shapes between the characters’ platform and the egg’s goal. A change to a character’s geometry or orientation affects the mirrored arrangement you are trying to use.
After fixing one surface in Mocking Birds, check the next. Plan a chain of receiving edges so the egg stays supported on its way to the destination.
Read the egg’s next landing surface
Find the egg, its goal and the surface immediately beneath or ahead of it. Inspect that edge before changing a distant part of the route.
Then look one transfer farther. A useful first slope still needs a receiving surface where it sends the egg. If the second section points away from the destination or leaves an awkward gap, correct that part before expecting the whole route to work.
Use the live board to inspect how a change affects its mirrors. Do not assume every repeated surface follows a memorized angle formula.
Assign one shape adjustment at a time
Keep one partner’s pose stable while the other changes a boundary. That makes the mirrored result easier to understand.
Test a slanted edge when the egg needs to move toward the next surface, or a receiving recess when it needs a resting position. Choose by the egg’s actual path and test the result. Neither works for every mirror arrangement.
- Identify the next surface the egg needs.
- Inspect its shape and orientation.
- Choose which character controls the boundary you want to change.
- Keep the other partner still.
- Adjust one shape or angle.
- Recheck the repeated route before another change.
Separate geometry from orientation. If the existing boundary is useful but faces the wrong way, rotate before cutting. If the boundary itself is wrong, reshape deliberately and inspect all its repeated copies.
Follow the egg through each handoff
Watch where the egg goes after it reaches a surface. Does it stay supported, move toward the next receiver or pass beside it? That observation identifies the next correction.
Avoid making several changes while the egg is between surfaces. You can lose track of whether the miss came from the original route or the new pose.
| Route problem | Useful inspection |
|---|---|
| Egg leaves the first surface incorrectly | Its supporting edge and direction |
| First section works, next section misses | Receiving position and orientation of the next mirror |
| One adjustment changes several boundaries | All repeated copies of that character |
| Egg reaches the goal area but completion stalls | Actual destination opening and final placement |
| Too much paper has been removed | Reform the affected character and rebuild its boundary |
Do not discard a working first section while correcting the last one. Preserve the stable partner where possible and inspect the effect of a single change.
Use the destination to judge success
Judge the mirrored shapes by whether they guide the egg home. They can work without being symmetrical or visually neat. Follow the completion display and the egg’s placement at the marked goal.
The Mocking Birds chapter begins at 06:30. Later mirror boards such as Mirror River use different arrangements, so recheck their receiving surfaces rather than carrying over every angle.
For shaping complementary boundaries, see Shape Match. For slower alignment, check the controls guide.
FAQ
What do the paper mirrors do here?
They form the repeated surfaces used to guide the egg. Inspect their geometry and orientation as a route.
Should I adjust both partners together?
Change one pose at a time while learning the route. A stable partner helps you see which boundary caused the result.
Do I need an exact rotation formula?
Inspect the live mirrored arrangement after each adjustment. Use the egg’s next receiving surface to judge the angle.
Why does fixing the first surface not solve the board?
The egg still needs a connected route through the next surfaces and into its goal.
Should the finished mirrors look symmetrical?
The objective is the egg’s destination. A useful route matters more than a symmetrical arrangement.
