This mod adds many flavors of gum to Minecraft. Every time you eat gum, it refills one bar of hunger and gives you a potion effect depending on the flavor of gum. There are six stages of gum: Gum, Partially Chewed Gum, Somewhat Chewed Gum, Mostly Chewed Gum, Chewed Gum, and Flavorless Gum Wad (Which can't be eaten). Once eaten, gum will have a chance to move on to the next stage, or it might stay the same. Once you chew your gum enough, it will become a flavorless gum wad (remember those?). These are completely useless and should be thrown away.
Then substitute the apple for:
Bubblegum: Pink Dye - Jump Boost
Watermelon: Melon - Absorption
Cinnamon: Red Dye - Fire Resistance
Spearmint: Lime Dye - Haste
Grape: Purple Dye - Invisibility
Original: Light Grey Dye - Speed
Orange: Orange Dye - Night Vision
Icy Mint: Light Blue Dye - Water Breathing
Apple: Apple - Regen
Fill the crafting table up with red, yellow, orange, lime, lapis, purple, and magenta dye, cake, and a flavorless gum to get Rainbow Gum.
It fills up 4 hunger bars, and I'll leave it to you to figure out what else it does.
I know it says you are the poster, I just wasn't sure if you were the one who actually made the mod. Anyway, I'm doing a cool YouTube series with this mod. I'll PM you a link once I've got a few episodes.
