It's very important! First, you'll need a GIRL. (If you don't have one-don't even THINK about getting a ichigotchi!)
Then, you'll need to hope you get a toddler that can get you into the meme family. Ichigotchi is a teen on v4, so you'll only see her a little bit. Your best hope of getting into the meme family is by getting a mizramatchi. She has the MOST chance. (I'm going to go study toddler getting, in other words, how to get certain toddlers, but for now, play games that get you "sparkle" points-dance is one, explore the others!) When it's time to turn into a teen, cross your fingers- you're not certain you'll get a ichigotchi, but you MAY get a young memetchi!
