I used Serebii because it's faster than Bulbapedia which is incredibly slow if your using a phone and it says here that you can catch a Crabominable in the Berry Fields in Alola next to route 2 but this is not true.

I spent half an hour trying to get Crabominable in the berries, I kept turning off and on my game and it never showed up and then I asked both ChatGPT and GrokAI how to get Crabominable in the Berry Fields and it turns out that it doesn't actually show up in the Berry fields and the berries underneath the tree in that place never contain a Crabominable and you have to look elsewhere.

So essentially this website is lying.
