While the game is loading and you see the text Loading... floating around everywhere, you can use your control stick to stop it and move it around as you like.
Only available in only one location, very fast and chickens out of most fights if you hit it or get too close to it, the Golden Goose is a real pain to capture in order to complete your card collection. Here’s a really cool trick.
Before you start, equipe your deck with the Vampire Bush card.
Once in the Grenfoel Church, run around the right upper side (where you got the Green Candle). When you get into a battle where a Golden Goose is running around, attract the other monsters away from the Golden Goose (the Goose will not come near you) and kill them using a close range card (a weapon card for example) so that you do not hit the Golden Goose. When only the Goose remains, place the Vampire Bush card far from the Goose and let it suck its energy until there’s only 1 or 2 bits left and then recall your Vampire Bush card (R Trigger + whatever button it was assigned to).
Finally, do a capture card technique (L Trigger + a card button) by staying a few feet away from the Goose.
And voila, you now have the most useless card in the game. Well not quite useless, like every hardly useful card, it does help complete your collection and can be used as a capture card.
