Another weird fact:
A lot of games attend to "recycle" data from previous games, specially if that games are of the same developer.
Here in the LDW games, reuses thing like clothes, the mushrooms, even the mysterious and (in)famous yellow mushroom. Also we find "the same birds" in VF, VV3 and VV4. And now in VV4 even puzzles from the first three(hint,hint). Another example is in the Diner Dash series with the same clients.Or one more newer: Inca Tomb from Enkord. Inca Tomb uses images, music and backgrounds from Totem Tribe, and elements from others previous games.
Examples: the "mysterious statue" is in a bonus level along with the music from the (just i'll say one) Skull Island and a icy background.
