Minecraft Seed: 4842516370214958083
I found what i consider, the smallest Jungle biome i have ever found in Minecraft, is a sparce Jungle biome in a coast next to the ocean.
It only has 3 jungle bushes and some vines. It does not connect to a bigger Jungle biome.
The Minecraft version this seed is, is version 1.20.
