2) Then, send Friendly Felix a "Help, can you please give me a hint" message. send the tuning rod you receive to Prof Brickkeeper.
3) After that, go to the Creation Lab and upload a model having to do with MLN. While you are waiting, find someone with the new Friendly Felix's Concert arcade module and try to win the LU skin, the video, and some stuff which will help later.
4) After your module has been approved, go to the MLN challenge page, and click "go to download". Then click harvest. This will give you the blueprint for the retuned tuning fork. Next, go to Capt Jack Knife's page and get the blueprint for the sea monster bait, and Numb Chuck's page to get the Kata Sparbot blueprint.
5) Build 4 of each the Kata Sparbot (5 pellets and 5 cannon scrap) and the Sea Monster bait (5 pellets and 5 Koi Sushi). You can get cannon scrap and Koi Sushi at Capt Jack Knife and Numb Chuck's pages respectively. They each cost 10 plastic pellets. You can also get them by winning on other people's Friendly Felix's concert arcade module, which is a good idea if you are low on pellets, but high on tokens. As of 2/26, I have a module that is kind of hard at the beginning, but on has 4 arrows, so you can leave the rest of the time. Ekingsley has an even easier one on his page, and I believe mwarvik3838 has a pretty easy one as well.
6) Trade for the Heliotrophic Harpoon Handle on Capt Jack Knife's page, and the Endless Ohm on Numb Chuck's page. Build the Retuned Tuning Fork.
7) Go to Friendly Felix's page and trade for the concert module. You are done!! Feel free to go to any of the networkers' pages and trade for stickers and loops. And be sure to go to other user's page and play their Friendly Felix Concert module.
