Master the waters of Route 119 with our Pokemon Emerald Feebas Tile Calculator. Feebas is notorious for appearing in only 6 random water tiles out of 440. Instead of fishing every single spot, use this tool to narrow down the coordinates based on your game’s internal seed.

Pokemon Emerald Feebas Tile Calculator Formula
The calculation uses a deterministic RNG seed derived from the Dewford Trendy Phrase:
$$Seed = (Word1 \times 256 + Word2) \oplus (TrainerID \pmod{65536})$$
$$TileIndex = (Seed \times 0x41C64E6D + 0x3039) \pmod{440}$$
Formula Source: Bulbapedia RNG Mechanics & Serebii Feebas Guide
Variables Used:
- Word 1 & 2: Numerical IDs associated with the two-word “Trendy Phrase” set at Dewford Town.
- Trainer ID: The 5-digit ID visible on your Trainer Card, used to further randomize the seed.
- Tile Index: The specific water tile number on Route 119 (1 to 440).

What is Pokemon Emerald Feebas Tile Calculator?
A Pokemon Emerald Feebas Tile Calculator is a specialized tool designed to predict which 6 specific water tiles on Route 119 will yield a Feebas encounter. In the 3rd generation games, Feebas location is not fixed; it changes whenever the “Trendy Phrase” in Dewford Town is modified.
Because Route 119 has hundreds of tiles and Feebas is required for completing the Hoenn Pokédex (and evolving into Milotic via beauty), this calculator saves players hours of repetitive fishing by narrowing down the probabilistic locations using the game’s internal math.
How to Calculate Feebas Tiles (Example)
- Retrieve the numerical IDs for your current Dewford Trendy Phrase (e.g., “GREAT EATING” = 12, 45).
- Note your Trainer ID from the game menu (e.g., 12345).
- Enter these values into the calculator above.
- The tool generates a list of 6 tile indices (e.g., 42, 156, 210, etc.).
- Fish in these specific locations on Route 119 to find your Feebas.
Frequently Asked Questions (FAQ)
How often do Feebas tiles change? They only change if you talk to the boy in Dewford Town and change the Trendy Phrase. Otherwise, they remain the same for your save file.
Does the rod matter? No, you can use the Old Rod, Good Rod, or Super Rod on the correct tiles.
Is Feebas 100% on those tiles? It has a 50% encounter rate on the designated tiles, while other tiles have a 0% encounter rate.
Can I use this for Ruby/Sapphire? Yes, the mechanics are largely identical across all Generation III Hoenn games.
