To get an itchogotchi on v4 make sure you have an mizutamatchi or puchiti or mohitamatchi as a toddler (prefferable mizutamatchi) and take average care
xXStarlightXx, I agree with you, but you can get BOTH Ura Memetchi and Memetchi on the V4.5. Now, I don't know how to get a female universal teen on V4.5 since I haven't experienced it yet, but you can get the Memetchi with wings (Ura Memetchi) on your V4.5 by getting a female baby, a pink toddler with arms, raising it to Ura Young Memetchi, then raising it to Ura Memetchi by having the most star points (gorgeous).
