Pokémon Gold and Silver/Route 29

'To get to Mr. Pokémon and complete your errand, first head west out of New Bark Town. Take the long way through Route #29 (through the grass near the center of the map), pass through Cherrygrove City, and take a short walk north to Mr. Pokémon's home on Route #30. But with only one Pokémon to protect you, it won't be an easy journey.'

The Adventure Begins
You can only be attacked in overworld Routes when crossing through the tall green grass. Unfortunately, there's a lot of that grass between New Bark Town and Cherrygrove City, so run from strong opponents when you're weak and use Berries and Potions to heal when necessary. If your Pokémon gets hurt too badly, return to New Bark Town and heal at Professor Elm's lab.

There's a wide variety of Pokémon on Route #29, and you'll not that the Pokémon you encounter change based on the time of day. But without any Poké Balls to capture them in, your only choices are to fight or run.

Calendar Event #1: Tuesday's Child
On the ledge in the very center of the route (above the white path leading north), you'll find the first of seven siblings who each appear at one spot on Johto, on one specific day of the week. Tuscany here only appears on Tuesdays', and only after you beat the Gym in Violet City. It can be a pain to remember to come back, but it's worth it: She gives you a Pink Bow that, when equipped, powers up all of one Pokémon's Normal attacks.

Pick your first Daily Berry
The bulbous trees like the one found in the northwest corner of Route #29 (to the left of the Route #46 gate house) contain one of a variety of berries that can be used or equipped by your Pokémon (select a Pokémon in your party and choose Item). The Berry found in this tree will recover 10HP to a wounded Pokémon.

They grow back every day, so if you come back tomorrow, a fresh berry will be waiting.
