Sky-Blue Spiny

Sky-Blue Spinies (or S. Blue Spinies) are variants of Spinies that are found only deep underground, in the Pit of 100 Trials of Paper Mario: The Thousand-Year Door. They are thrown by Dark Lakitus and can be found on floors 61-70 of the dungeon. They are stronger than normal Spinies and attack by charging. They can sometimes curl up and hide in their shell, making them impervious to any attack, even those that bypass defense.

They highly resemble Spinies, except instead of red, their shells are blue similar to the Spiny Shells in the Mario Kart series. Additionally, their skin is slightly darker like the Dark Lakitus that throw them. This gives them a resemblance to Buzzy Beetles, so much so that the German version of the game refers to them as "Käfer-Stachis", meaning "Buzzy Beetle Spinies". However, they lack the usual qualities of Buzzy Beetles, such as resilience to fire.

In the English version of the game, it is mistakenly stated that Dark Lakitu's Sky-Blue Spinies hatch from "pipes" in Goombella's Tattle for both enemies. However, the supposed "pipes" which spawn Sky-Blue Spinies are actually regular blue Spiny Eggs. Their name is the result of a mistranslation: Spiny Eggs are referred to as ｢パイポ｣ Paipo in Japanese, which comes from a well-known Japanese folktale but can also be interpreted (incorrectly, in this case) as an approximation of the English word "pipe" into Japanese katakana. Despite this mistranslation, ｢パイポ｣ Paipo is correctly translated as "Spiny Egg" elsewhere in the English text of Paper Mario: The Thousand-Year Door, namely with regard to the standard species of Spiny fought in the game.
