What does it do
Jenny Mod is a character-interaction mod rather than a large content overhaul. It adds one or more companion NPCs, a dialogue system, gifting, follow / stay / guard commands and matching animations. It does not rewrite building, mining or world generation.
What it does
Adds a companion NPC (Jenny Belle) and, over time, a wider cast of themed companions. Adds a dialogue window with talk, greet and gift actions. Adds relationship-driven progression that unlocks extra dialogue and animations. Adds a small item set (gift items, potions, jewellery) and a distinctive spawn house in Plains biomes.
What it does not do
Core building and crafting mechanics stay intact. Mining, farming and traditional survival play the same. Vanilla blocks and world generation are not replaced. The mod does not add a new dimension or overhaul combat systems.
