📋 About This Mod
After becoming the laughing stock of his peers for his 'outrageous' theories regarding the smoluanu, geologist Professor Jasper Thomas has returned to Pelican Town. Can you help him overcome his embarrassment? Or will he fall prey to his obsession?
Professor Jasper Thomas is a shy and polite geologist/anthropologist, recently returned to Pelican Town to further pursue his studies of the smoluanu. Obsessed with his work, and his pursuit for knowledge, can you help him realize that there is more to life?
He currently resides in a newly-added second storey above the Archaeology House - which is also home to a collection of archives (See below for more details)!

Jasper's 6-heart event involves multiple events and sprite/schedule changes. It has been re-written for multiplayer, and contains two Broadcast events.
Only the host can trigger the 6-heart event.
(I have not yet been able to test the co-op mode, and thus it is considered in beta.)
Jasper's six-heart event takes at least one ingame month to play through. During this time he something very dramatic happens. If you have any concerns about this, please let me know and I shall endeavor to address them.
A couple of things to note:
[] Dwarf won't appear in game until you've either seen Jasper's 6-heart event through fully OR you have the translation guide.
This has been disabled and is now configurable, should you want a more immersive experience. If adding into a save where you have already befriended Dwarf, you will get a bonus cut scene. []Added gift tastes, a birthday and dialogue for Gunther. You can befriend him now (he doesn't leave the counter though). He will also always end the conversation by commenting on your lack of donation. NOT ACTIVATED WITH SVE/BGAM/ME.
[]Added gift tastes and dialogue for Marlon (conditional/configurable) NOT ACTIVATED WITH SVE/BGAM
[]Changes made to Dwarf: Dwarf cave interior changed pre-meeting them for story-related reasons.

With nearly 4,000 endorsements and 297,000 downloads, it's a popular addition for players seeking new characters.
✨ Key Features
📊 Pros & Cons
✅ Pros
- Huge community trust with 3,913 endorsements and nearly 300k downloads.
- Standalone version means you don't need East Scarp to enjoy this character.
- Recently updated (Dec 2025) so likely compatible with current game versions.
⚠️ Cons
- Explicit warning not to install alongside East Scarp 3.0 — potential conflict if you use that mod.
- Only one NPC added — if you're looking for a larger content pack, this might feel limited.
For Stardew Valley players who want to add a new, well-received NPC without overhauling their game. If you're already using East Scarp 3.0, skip this standalone version to avoid conflicts. Perfect for those who enjoy character-driven content and want a fresh face in Pelican Town.
💡 Beginner Tips
- If you use East Scarp 3.0, do NOT install this standalone version — it will conflict.
- Make sure you have SMAPI installed, as most Stardew Valley mods require it to run.
- Place the mod folder in your Stardew Valley 'Mods' directory, then launch the game with SMAPI.
