King Awowogei's location
Inspect King Awowogei in the Lumbridge castle dining room.
Travel to Ape Atoll. Head to the Southeasternmost building in Marim.
If not already, equip any monkey greegree and the monkeyspeak amulet.
Talk to the Elder Guard.
Talk to Awowogei.
If you do not already have a banana and monkey nuts, head west of the temple to Solihib's Food Stall and buy one of each.
Head to the Temple of Marimbo to the north of Awowogei's seat.
Talk to the three wise monkeys in the north-west corner of the temple.
Talk to the three wise monkeys two more times (first discussing the banana and then the same for the monkey nuts).
Obtaining the Ingredients
Note: Each of the three following can be done in any order. The wise monkeys will eat any Red bananas or Tchiki nuts you have if you return to them and you may burn the dish or accidentally eat it whilst handling it, therefore it is a good idea to collect more than one of each.
Head to Crash Island and enter the pit east of Lumdo.
Lower level combat players may find it useful to turn on Protect from Melee before entering the pit and also having an emergency teleport. Anti-poison is also useful.
Kill a snake to get a snake corpse.
The Red Banana
Find the red banana tree on the coast west of Marim.
Equip a gorilla greegree.
When red bananas are visible on the tree, use a rope on it.
Slice the banana with a knife. (Tool belt knife works. Once the previous one is sliced, you can collect another.)
Head south of Marim to the Ape Atoll Agility Course.
Equip the ninja greegree.
Proceed through the course until reaching the hole right after the rope swing.
Enter the hole and pick a monkey nut from the bush.
Grind it with a Pestle and mortar. (Tool belt pestle works. Once the previous one is ground, you can collect another.)
Climb up the rope and finish the course.
Freeing King Awowogei
If below level 70 Cooking, make sure to have the boost at this part.
Use the snake corpse on either the red banana slices or the tchiki monkey nut paste to prepare an uncooked stuffed snake.
Enter the trapdoor near the eastern wall of the temple.
Walk down one of the wooden platforms and Enter the crack in the east wall between the wooden platforms, called "Exit".
Equip the zombie greegree.
Walk across the coals and Use the uncooked snake on the long rock.
Head to Lumbridge Castle and use the stuffed snake on King Awowogei. (Be careful not to eat it.)
