While Niantic is still checking the ongoing curveball bug in "Pokemon GO," the developer made some recent changes to the AR title's Egg hatch pool. Some of the tweaks include the removal of some notable critters in the roster.

Massive egg pool changes

Albeit being vocal about the game's major updates, Niantic somehow made things a bit low-key with egg pool tweaks. However, "Pokemon GO's" Silph Road community revealed that quite a number of monsters were removed from the game's egg pool, though it was replaced with a new roster.

According to the new post, nine Pokemon were noticed to be no longer appearing as hatchlings.

The following monsters are confirmed to be booted out from the egg pool roster: Goldeen, Staryu, Yanma, Ekans, Magnemite, and Vulpix. The starters Charmander, Squirtle, and Bulbasaur were also removed, though these creatures can still be encountered in the wild.

These Pokemon were observed by most players to be no longer hatching from eggs as early as July which is the game's anniversary month. However, Niantic replaced these gen 1 creatures with gen 2 counterparts as they were introduced during the same time period.

Gen 2's starter trio - Totodile, Chikorita, and Cyndaquil can now be hatched in eggs. These monsters are also clustered under rare hatches alongside Houndour, Snubbull, and Teddiursa.

Meanwhile, Spinarak, Natu, Swinub, Chinchou, Marill, Wooper, and Hoppip were tagged as uncommon in the egg pool.

Shorter hatch requisites

Egg distance changes were also tweaked in some of the Pokemon in the pool. The tweaks were done at the tail end of "Pokemon GO's" anniversary event as these monsters can be hatched from a shorter distance.

From the initial 10-kilometer hatch distance, Mantine, Pineco, Gligar, and Chinchou can now be hatched at half the travel length.

Niantic also made some changes in some of the Pokemon' rarity status. Some of the notable tweaks include Mareep which became an 'uncommon' from its original 'rare' status. Both Skarmory and Porygon's super rare tags were also tweaked to 'rare' and 'uncommon' respectively.

Pichu was also toned down and is now a 'common' hatch from being an 'uncommon.' Meanwhile, both Gligar and Pineco rose in the ranks as they are now deemed as 'super rare' from being an 'uncommon' as well.

Harder to come by

Hyper rare's were also pointed out by the "Pokemon GO" forum. Four species of Pokemon were bagged under that category which includes Girafarig, Shuckle, Dunsparce, and Wobbuffet. Check out a video about the game here:
