There was a mod pack out that a fan made already, but that one was a bit outdated so I decided to update it and add more mods from the latest episode (ep 90) of Candy Isle Modpack/series (stacyplays and amylee33). I just made this updated version to play with my twin, so this probably won't be updated unless we decide to play it again.
Mods included: NEI, Mermaid Mod, Oceancraft, CandyCraft, Aquatic Abyss, Fairy Mod, fairylights, Pet Bat, Crystal Hearts, Backpacks, Pokeball Mod, eternal frost mod, Craftable Horse Armor, optifine, journey map, world edit, MrCrayfish Furniture Mod, and Chisel's
NOTE: To get Mermaid tail's mod to work, delete optifine in your mods folder (C:\Users\YourUserName\AppData\Roaming.technic\modpacks\candy-isleextras\mods) and edit your skin at (1,0) pixel with these following colors at this website: http://www.planetminecraft.com/mod/1710172-forge-mermaid-tail/. This is only optional though if you're okay with having lag. If not, you can keep optifine, but you will not be able to see the tail from the Mermaid Tail's mod.
