Deep In Ochre Woods: Togepi Egg
When in Deep In Ochre Woods, go to the cave at the edge of the woods. Command Pikachu to come to you -- you may also need to tell him to look. He will look in the cave and find a Togepi Egg. Abra will come down and take the Egg. Visit Abra's shop and the Egg will be there. Visit often enough and the Egg will hatch.
Field Trip Part 2: Hidden area
Approach the largest tree. Command Pikachu to came to you and you will be able to enter the tree and get to Abra's shop.
Field Trip Part 2: Watering Jug upgrade

Pikachu's Daring Days: Pirate's Sword
Go to Pikachu's Daring Days and select Cobalt Island (The Treasure Hunt, Part 2). Go to the other side of the island and look around. Eventually, you will find a path leading up to a pirate fort. Try to keep Pikachu from finding the treasure chest. Using view mode, tell Pikachu to "Thunderbolt" the cannon facing away from the treasure chest. A loud blast will ring out. When the smoke clears, you will notice that all the chests will be unearthed, allowing you to simply follow the directions on the signs. If you did not open the chest inside the fort, opening it now will give you a pirate's sword.
Pokemon Picnic levels: Extra points and secret areas
There are secret areas in all Pokemon Picnic levels. They are all in the same place. Find the odd spot in a wall. Go in it (and if you cannot see, turn up the color). There will be a magnet and a few bolts there in Pokemon Picnic 1. Pick them up for more PikaPoints. In Pokemon Picnic 2 and 3, there will be a Golden Apple. Pick it up for 500 PikaPoints.
Pokemon Picnic 3: Lucky Hook
In Pokemon Picnic 3 you can buy the Lucky Hook from Abra's shop. Pikachu needs to be nearby to enter the shop. Once you leave you cannot reenter until the next day.
Pokemon Picnic 3: Better Water Pokemon
Play in Pokemon Picnic 3 and go to Abra's shop. Buy the Lucky Hook, then go fishing anywhere. Some of the different Pokemon you can catch include the following.
Olivine: Pollywag, Pollywirl
Cobalt: Kingler, Tentacruel, Seadra
Make Pikachu dizzy
Go to the Pikachu's Discover, Play, or Daring Days map and press the Analog-stick in any direction. You should see circles in Pikachu's eyes.
If you want Pikachu to do an attack, say one of the following: "Thundershock", "Thunderbolt", or "Thunder". Saying "Thunder Wave" or "Thunderpunch" will only confuse Pikachu, because he is only used to three attacks.
Play Pokemon quiz at any time
If you want to play Pokemon quiz, but Pikachu wants to go outside, say "Quiz Time". Pikachu will nod its head and start the Pokemon quiz. Note: Pikachu must be looking at you.
