Why did i spend all that time doing a quest just for the articuno to kill it self

i spent about 1 week spending money so I can beat the legendary birds quest and I finally beat it and I had to catch the articuno that's bull I spent 2 stacks of u balls on him when he was at 1 hp and nothing.

personally I think u should have given us the egg because it takes a lot of time to do that quest

 

I have no idea what you bought but this mightve saved you some trouble...

 

yeh I know that now that's my bad guys well I might save up to get a legendary bird egg
