Unlock costs

Candy needed for a cost-3 starter:

Passive ability
35 🍬
Cost reductions
20 / 50 🍬

The price only drops once you have hatched enough Grookey eggs: 22 🍬 after 20 hatches, 18 🍬 after 40 hatches, 12 🍬 after 80 hatches.
Friendship needed per candy

Expensive starters ask for fewer candies, but earn them far more slowly: Grookey needs 75 friendship per candy, while a cost-1 starter earns one every 25.
