Trivia Piñataさんのイラストまとめ

The face on chocolate coins belongs to Jeffe, an obscure character appearing exclusively on The P-Factor in TiP. This character design also appears in early concept art for VP1, so it must have been repurposed from some sort of scrapped character idea.

In VP1, a mysterious blue flower can be seen just outside the garden. This flower bears almost no resemblance to any of the flowers that can be grown in the garden. It's possible that it may have been intended to be obtainable, but was cut.

Due to a development oversight, in VP1, wildcard Eaglairs have no visible differences from regular Eaglairs. In a forum post @BIGsheep jokingly claimed all wildcard Eaglairs suffer from the genetic abnormality Situs Inversus. In TiP, wildcard Eaglairs were made visually distinct.
