Tinkle Pit/World 3

海の界域 (Umi no Sakai-iki) エメラルディア (Emerarudia)

GOOD LUCK!!

Stage 11
As this world's naming suggests, it is based upon Emeraldia (1993); many of the characters from its "Adventure Mode" can be sighted swimming past in the background as a result. This stage contains four Pookas (from Dig Dug, 1982) and four Moonils but only four of them are present at the start - and if you manage to kill all four of those initial enemies with a single return of your Tinker Ball an eleventh Bonus Flag will fall down from the top of the screen (but its number shall be back to 1, if you collected the first ten, so its point value shall be back to 10000). It is also worth noting that the Bonus Character for this stage is a 300-point Strawberry, which has previously appeared in: Pac-Man (1980), Ms. Pac-Man (1981), Pac & Pal (1983), Professor Pac-Man (1983), Pac-Land (1984) and Pac-Mania (1987) - and two more Pac-Man bonus items (three, if you count the Galaxian Flagship) may also appear later.

Stage 12
This stage contains two Heitai (from Toy Pop, 1986) and eight Moonils (but only six of them are present at the start); because the Bonus Flags' numbers repeat from the beginning once you have collected a tenth one, they will no longer be mentioned. The Bonus Character for this stage is a 300-point Kapi - which has previously appeared in Xevious (1982), Super Xevious (1984) and Solvalou (1991), and for the last of these games it was in polygonal form.

Stage 13
This stage contains two Heitai, six Fygars (also from Dig Dug) and one Stinger (but only five of them are present at the start); it is also worth noting that the Bonus Character for it is the 400-point Mona Lisa, which has previously appeared in Mappy (1983), and there there were two of it in every mansion.

Stage 14
This stage has four Fygars, four Moonils, and one Stinger (but only five of them are present for the start); it is also worth noting that the Bonus Character for it is a 410-point Green Furossa, which has previously appeared in Grobda (1984). Ironically, Grobda itself makes no kind of appearance in this game.

Stage 15
This stage has three Heitai, one Pooka, and four Fygars (but only four of them are present for the start); it is also worth noting that the Bonus Character for it is a 500-point Hoblin, which has previously appeared in Libble Rabble (1983) and Genpei Tōma Den (1986), only not in a blue cloak for either title.

Stage 16
This stage contains one Pooka, three Fygars, three Moonils, and one Stinger (but only four of them are present for the start); it is also worth noting that the Bonus Character for it is a 500-point Safe, which (like the Mona Lisa), has previously appeared in Mappy (1983). Once you have cleared this stage, you shall proceed to the game's fourth world, Okashi no Sakai-iki Sweet Shop (お菓子の界域スイートショップ) - which, once again, features six stages.
