What to bring while looking for a Jungle biome in Minecraft?

I'm looking for a Jungle biome, I have been for a long time. I traveled over 3,000 blocks away, but to no avail. (TWO Flower Forests?!) I was wondering what to bring. I have fish, a sword, tools, a diamond block in case a tool breaks, torches, a flint and steel for the forest next to my house…(LOL)and of course, my armor. I'm playing in Peaceful, so I don't want to bring food. I think I'll bring my best horse too, since horses travel fast. I'm trying to take a break from attempting to get Wither Skeleton Skulls… I only have 1… I've found some rare things, like TWO pink sheep almost next to each other. And, like I said above, two Flower Forests. Two Ocean Monuments. Wow, everything comes in pairs xD
