Wouldn't it be more efficient to have a Rhyperior kill the Aggron? Its Earthquake is much stronger than Bastiodon's. Also, how many cookies does this make?
No, Bastiodon uses metal burst and instant kill aggron because it is made of metal and it bursts it makes one cookie did you not see the recipe??
1 Bastiodon to kill all the aggrons
1 large bowl to catch all the blood
1 cookie
