What is the mystery egg in Pokemon SoulSilver?

Answer 1

togepi and this togepi will have a very strong psychic move known as extrasensory. Iw will be 1 great fighter long before it is level 5, when you battle it against some low levels on route 29 and 30. You see a poison or fighting type, and it is exceptional.

presently my togepi is a strong togekiss at level 100. It still knows extrasensory, and with the ghost move shadow claw, it is good against psychics. Until I taught it shadow claw, it had a little bit of trouble with wobbuffet. but with the shadow claw ghost move it can easily hold its own against ghost and psychics as well as poison and fighting types.

because it is part normal, it is immune to ghost type attacks.

Answer 2

"I believe the mystery egg is a manaphy egg."

Well it is not.I walked to a area in the grass and it said "huh?" and the egg hatches to a Togepi.But it was a good guess dude.At first I was thinking it would be the same.After all,Togepi and Manaphy are both soooo cute!
