Hey /vp/
Im not a regular here, but if one of you guys could tell me what game this is from, or if it really exists I would appreciate it.
It is basically a massive clearing inna cave with a massive fish like pokemon silhouette in the water before initiating battle. I remember this so vividly being a kyogre fight, but I literally cant find anything about it anywhere, so im starting to think my kid mind may have dreamt in up
