This is my round 3 entry to damasosos92's The Skunkworks League.

The prompt for this round was to create a permaculture (allowing interactions) using two genres from a predetermined selection. The grid must be of 37-82 cells with a hole of a given shape removed from the grid.

Other puzzles from this round and made using this prompt can be found by searching for [TSL] and [S1T3] in the title.

Rules:

• Permaculture: Divide the grid into two non-overlapping orthogonally connected areas. One area must follow aquarium rules and the other must follow kazunori room rules.

• Aquarium: Fill some cells with water such that the water is at a resting state in its own region, following the laws of physics (i.e. within a region water must be level). Values in cells orthogonally adjacent to the aquarium area represent the number of water filled cells seen by the clue in the row or column or both separately where applicable (e.g. a 2 adjacent to both an aquarium row and column will see 2 water cells in the row and 2 water cells in the column). Black hole cells and other kazunori cells block vision.

• Kazunori Room: Place a whole number from 1 to N into each cell so that each region contains each number from 1 to N exactly twice each, where N is half the number of cells in the region. Two numbers of the same value within a region must be orthogonally adjacent. No 2x2 area may consist of cells which all contain the same number. A circled clue represents the sum of the numbers in the cells it touches.

• Border Clarifications: The two areas may split a given region, if this happens the border between the two areas acts as a region wall. A kazunori sum on the border of the two areas will only give the sum of the kazunori cell.

• Solution: Highlight aquarium water cells in blue, air cells in green, and kazunori cells in light grey. Fill aquarium water cells with 9s and air cells with 0s.
