Stage 17
This stage contains four Pookas (from Dig Dug, 1982), three Moonils, and one Clipper (but only four of them are present for the start); the Clippers can also cut the lines between you and your Tinker Balls, in which case the Tinker Balls shall speak the text "Pick me up, 1/2P!" and you shall have to walk back over to them. It is also worth noting that the Bonus Character for this stage is an 800-point Galaxian Flagship - which has previously appeared on Galaxian (1979), Pac-Man (1980), Galaga (1981), Gorf (Midway Games, 1981), Dig Dug, Super Pac-Man (1982), Pac-Man Plus (Bally Midway, 1982), Pac & Pal (1983), Professor Pac-Man (Bally Midway, 1983), Pac-Land (1984), Super Xevious (in silver form, 1984), Genpei Tōma Den (in white, black and pink form, 1986) and Pac-Mania (in normal and silver forms, 1987), but it was also originally intended to appear in Pistol Daimyo no Bōken (1990).
Stage 18
This stage contains three Fygars (also from Dig Dug), two Moonils, one Stinger and two Clippers (but only four of them are present at the start); it is also worth noting that the Bonus Character for it is the 1000-point Nyamco (or "Goro") who previously appeared in Mappy (1983) and Hopping Mappy (1986).
Stage 19

It is also worth noting that the Bonus Character for this stage is a 2000-point Taitorian - who has previously appeared on Motos (1985).

Libble and Rabble themselves may later appear.
Stage 22
This stage contains one Pooka, three Moonils and two Timbots; it is also worth noting that the Bonus Character for the stage is a 4000-point Pink Molek, which has previously appeared in Phozon (1983). Once you have cleared this stage, you will proceed to Vs. Boss - which will see you facing off against the Moonil-operated Naka-G1, who is backed up by an infinite amount of Heitai (whenever you kill one, another one will get generated to take his place).
