There's no other thread for this so I'm going to vent here.
God fucking damn why do some Pokemon refuse to fucking spawn? Cyndaquil spawns in ONE CAVE in the entire Terarium and the fucker wasn't there at all, despite the upgrades and my map saying it spawns there. I ended up breeding the Mightest Mark Typhlosion to get Cyndaquil and Quilava's dex entries. Similarly Mudkip spawns in two pools in the Coastal Biome and I have been sitting here for two hours killing Araquanids, Alomomola, and Seadra and not a single one has spawned. What gives? Just give me ONE Mudkip. Christ, game.
