Jungle de Ikou!

"Jungle de Ikou!" (also known as "Jungre de Ikou") is a three-episode Original Video Animation (OVA) series released in 1997. It blends comedy, fantasy, and ecchi elements in an over-the-top, humorous narrative. The story revolves around a young girl named Natsumi Rokudou, who receives a strange necklace from her archaeologist father upon his return from a trip to New Guinea. The necklace turns out to be a talisman that holds the power of Mii, the spirit of the Earth. Natsumi can transform into Mii, a grown-up and voluptuous version of herself, who embodies the power of the Earth. Additionally, Natsumi must also deal with the awakening of two other spirits: Ongo, who is destructive but is fortunately small and usually harmless, and Nami, the water spirit, who isn't too happy about Mii's appearance. The series follows Natsumi's adventures and misadventures as she learns to control her new powers and deal with the other spirits.
