Teru-sama

Teru-sama (Japanese: カビチュウ Kabichū) is a glitch item that appears in Generation II. It appears to have no other use than to be sold for $19660. It is kept in either the key items case, or the items one. Teru-sama is a data filler between actual items (like Missingno. is filler between Pokémon).

Teru-sama can literally be translated from Japanese as "Lord Sunshine", coming from the words Teru (Sunshine or to Shine) and the suffix-sama (an honorific that shows extreme respect and is most often translated as "lord" or "master").

Despite popular fanon myth, Teru-sama is not the GS Ball; however, the item slot that the GS Ball is programmed into in Pokémon Crystal was an item slot containing the Teru-sama in Gold and Silver, as with the other Crystal-exclusive items (such as the Egg Ticket and Blue Card).

Teru-samas, through hacking, can be actually used. Two Teru-samas are actually usable. One brings up the Town Map. It displays the Kanto map in less than 1/10 of a second, and when returning to the item menu, the tiles become glitched. Another item is the Poké Flute, which works exactly the same as in Generation I, but remains silent.
