I use fisch to connect with my autistic son and his dream fish is nessie 😭

UPDATE: I have nessies! Thanks so much for the advice and the amazing player who gifted nessies. My son is going to be so happy - and it's going to mean so much to him that I managed to do this. Thank you!

UPDATE 2: He's so happy tonight - more than he was Christmas morning! also thanks to the player who came and gave us some free fish - you guys are amazing, thanks so much for coming through for us - after a rough week it's the best thing in the world to see him so happy!

I've made it to level 138, daily grinding as it's the only thing he loves to chat about, it's his special interest. I've gotten to enjoying it too, but it's mainly so we can chat. He's had a tough time, he's only 10 and recently had to move school as he couldn't cope.

He's really good on the game, around level 200, working through challenges and unlocking things. He talks about getting Nessie every day. He had me join discord to see if there was a way to trade but I really don't get it!

He's given me a kraken and a whale and I want to suprise him with a nessie! Is this even possible with my enchanted champions rod?! How do I do this?! Where do I go? Or what's the going rate to try and find someone to trade me for a nessie? Think I'm a bit out of my depths here as a complete Roblox newb!
