It's the eggs that aren't accepted in the daycare, pokemon do get
released, and disappear into a black hole. That is true, but eggs
don't do that. Unless they are special,event,quest,etc. (Since they
don't have an egg radar chip in the first place) If it didn't show
up, then you probably didn't have the chip for it. You can test
this by looking through the tall grass amounts,
mareeps,pichus,salandits are all common chaining pokemon so thats
why the amount of them is so high compared to the other pokemon.

People often think the PH sprites are bland. Do they shade? Well,
yes they do. You'll be surprised how much care is taken for these
sprites.
