Pokémon Diamond Version, Pearl Version, and Platinum Version - Honey Trees
There are 21 so-called "honey trees" with a yellowish tone. When the player slathers any one of them with Honey, a Pokémon can appear eventually. These are the trees:
- South Route 205
- North Route 205
- Route 206
- Route 207
- Route 208
- Route 209
- South Route 210
- North Route 210
- Route 211
- Northwest Route 212
- Southeast Route 212
- Route 213
- Route 214
- Route 215
- Route 218
- Route 221
- Route 222
- Valley Windworks
- Southeast Eterna Forest
- Fuego Ironworks
- Floaroma Meadow
When the player slathers a "honey tree" with Honey:
- If this tree is different from the last tree slathered or no trees were slathered yet this game, a group is chosen and a Pokémon species from that group is chosen.
- If this tree is the same as the last tree slathered (whether the tree has Honey on it or not), at a 90% chance a Pokémon species from the last chosen group for that tree is chosen, or at a 10% chance a group is chosen and a Pokémon species from that group is chosen.
360 minutes after the player slathers a tree with Honey (whether the tree has Honey on it or not), a Pokémon of the species determined previously, at a level from 5 through 15, will appear on that tree. The Pokémon will remain on the tree until the player encounters it or until 1080 more minutes have passed.
Using Honey at a place where a wild Pokémon could appear is the same as having a Pokémon use the move Sweet Scent.
Encountered Pokémon
The game uses the following list to determine which Pokémon will appear:
Pokémon Diamond Version and Pokémon Pearl Version
- Group 1 (20%) - Wurmple 5%, Silcoon/Cascoon* 5%, Combee 10%, Burmy 20%, Cherubi 20%, Aipom 40%
- Group 2 (70%) - Combee 5%, Burmy 5%, Cherubi 10%, Aipom 20%, Heracross 20%, Wumple 40%
- Group 3 (1%/0%) - Munchlax 100%
- Group 4 (9%/10%) - No Pokémon will be encountered. In this case, the Honey is still used up, the tree is still considered the "last tree slathered", the last group chosen for that tree is considered to be group 1, and the message "There is a sweet scent in the air..." is shown when the tree is checked again.
*Silcoon in Diamond version, and Cascoon in Pearl version.
Platinum Version
- Group 1 (20%) - Combee 5%, Wurmple 5%, Burmy 10%, Cherubi 20%, Aipom 20%, Aipom 20%
- Group 2 (70%) - Burmy 5%, Cherubi 5%, Combee 10%, Aipom 40%, Heracross 20%
- Group 3 (1%/0%) - Munchlax 100%
- Group 4 (9%/10%) - No Pokémon will be encountered.
"Munchlax Trees"
Four of the 21 trees are so-called Munchlax trees. For these trees, there is a 1% chance that a Munchlax will appear on them, and Munchlax won’t appear at all for the other trees. Whether a tree is a Munchlax tree depends on the player’s 32-bit Trainer ID:
- ID is set to the player’s 32-bit Trainer ID.
- D is set to (ID mod 256) mod 21.
- ID is divided by 256 and rounded down.
- C is set to (ID mod 256) mod 21.
- ID is divided by 256 and rounded down.
- B is set to (ID mod 256) mod 21.
- ID is divided by 256 and rounded down.
- A is set to (ID mod 256) mod 21.
- If A and B are the same, B rises by 1, then set to 0 if the result is 21.
- If A and C are the same, C rises by 1, then set to 0 if the result is 21.
- If B and C are the same, C rises by 1, then set to 0 if the result is 21.
- If A and D are the same, D rises by 1, then set to 0 if the result is 21.
- If B and D are the same, D rises by 1, then set to 0 if the result is 21.
- If C and D are the same, D rises by 1, then set to 0 if the result is 21.
- The Munchlax trees will have IDs of A, B, C, and D.
- In the steps above, "X mod Y" means "the remainder of X divided by Y."
