You catch a gible then train it till it evolves into Gabite then into Garchomp.
Okay, so there is only one place in Sinnoh that you can catch Gible. You can catch Gible on Route 206 in Wayward Cave under the Cycling Route (Eternia to Oreburgh)
no. you would have to catch a gible yourself. it is found in the hidden cave under cycling road on route 206.
You catch it in the cave below the cycling road then you go up as far as you can and there should be a cave.
No. You just need to go to Wayward Cave B1
no
Gible are all over in Wayward Cave.
Gible cannot be caught in Black or White.
in wayward cave
Gible is not available in this Pokemon version in the wild. to acquire Gible, you must beat the Elite Four and transfer this Pokemon through the Poke Transfer Lab located on Route 15. You must have Gible in your PC in another Pokemon game used on a DS (Diamond, Pearl, Platinum, Heartgold or Soulsilver.) This is true for all Pokemon you want/need in previous generations.
Pokemon #109: Gible. Pokemon#108: Spiritomb.
