Grassland Hill

Grassland Hill is the first area in Pikmin: Spider Attack. In the crash landing spot, there is a small field with some Pikmin. Going foward is a massive field with obstacles, enemies and Red Pikmin. The Onion is located in a patch of tall grass. Pikmin will open it up for Olimar, and come to him.

Enemies
The first enemy seen in the area is a dweevil, but the first enemy encountered is a Dwarf Bulborb. Then in the giant field, there is 3 dwarf bulborbs. After a obstacle, there is a Boss Bulborb, which is a Normal Bulborb but much more giant. It is very easy. To the next day you should see 3 Orange Bulborbs in the center of the giant field, 1 Red Bulborb and 3 dwarf bulborbs to the left, and to the right there is 2 dwarf bulborbs. Past the orange bulborb is 3 Red Pellet Posies.

Obstacles
The first obstacle in Day 1 is a Pikmin Weigh obstacle to the right of the giant field. You will need 11 Pikmin to be able to get to the upper area. On the upper area there is the Tempature Mechanism, and 10 Red Pikmin sprouts. When you return the Tempature Mechanism to the ship, a gate will be unlocked to the left of the giant field, past the gate there will be the Boss Bulborb. When you defeat the Boss Bulborb the day will end.

Ship Parts
The Tempature Mechanism can be collected after Olimar completes the Pikmin Weigh obstacle. In Day 2, in the area where the Boss Bulborb used to be, there is a Ship Fixer. When you return this part, it will fix Olimar's Ship a bit, to be used more. It also lets Olimar travel to the Birch Forest.
