Shape Sprites
Ask two shape sprites to become bridges or ladders while you cross the islands. Sprite A is centered at column 2, row 3; B at column 4, row 3. A bridge supports horizontal travel through its three cells; a ladder supports vertical travel. You cannot walk through the side of a ladder or bridge. Select A or B, then choose its form. The center stays occupied in either expanded form, so you can turn a bridge into a ladder while standing at its center. Folding removes its support and can drop you if no island remains beneath you. Collect the seals on the left and right middle islands, then reach the upper-right portal within 24 walks/form changes. Gray island cells are always safe.
