gollark: Would the egg they're offering not end up going to 6D0H anyway if you took it?

gollark: Assuming my maths is right, only about 30000 5-long `bug` codes can exist.

gollark: I would say "a destiny of being traded on to code collectors for some other dragon" but apparently not.

gollark: Or "So, XD x".

gollark: Also, presumably the rarer alts of common ones, like red dorsals and tan ridgewings.
