7: Inside and outside the whale
Distinguishes who uses an item and where to deliver it from merely collecting it. Descriptive names identify locations rather than reproduce official translations of every UI label.
| Target | Required action | Then |
|---|---|---|
| Breathing tube | Receive from the fish outside | The sister dives beneath the belly. |
| Pirate doll | The brother pushes it through the belly exit | The sister collects it and uses it on the floating toy for the glowing bottled creature. |
| Glowing book | Read pages using the bottle's ultraviolet light | Clue to creature order beneath the belly. All picture layouts not included. |
| Electric bait | Match the belly creatures and take the electric bug | The sister throws it into the whale's mouth to the brother. |
| Fisher | The brother gives the bait | Receive suction cup/fish, take the key from the toilet, and push it to the sister. |
| Pirate seagull | Give it fish and win the crab game | Have it carry the chest and open it with the brother's key. |
| Submarine | Move obstacles using the chest's controls | Head toward and call the upper boat's signal. |
Crab board: 4 vertically or horizontally
Race to align 4 orange crabs vertically or horizontally. Movement continues to the next obstacle, so do not use ordinary single-square movement assumptions.
Block the opponent's three/four-in-a-row while creating your own. Opponent moves vary; no fixed action sequence for every match is included.
8: Wake the sleeping creature
Distinguishes who uses an item and where to deliver it from merely collecting it. Descriptive names identify locations rather than reproduce official translations of every UI label.
| Target | Required action | Then |
|---|---|---|
| Crab's cork | Chase it 3 times into the hole | Take the cork, block the red light's entrance, and take the light. |
| Light plant | Place the red light | Take the conch from the approaching crab. |
| Sleeping creature | Use the conch as a mouth amplifier | Proceed to the 4 jellyfish puzzles. |
| Jellyfish 1 and 2 | Ascending dot count / new moon to full moon | Do not order matching pictures solely by apparent color. |
| Jellyfish 3 and 4 | Combine left/right lines / mirror symmetry | Full-position picture arrangements remain incomplete. |
