A happy new year for this community and for Frontier Developments. I thought about Zoo Tycoon 1 and I remember that this game exists of an insects-house, a bird house and if I'm right also a butterfly house. To get them in use in Planet Zoo it would be great to get more vivariens. For the smaller birds I think the Vivarien size should be enough. For the bigger ones it would be great to get more Vivarien sizes (1x1, 2x2 and 3x3). The height of the vivariens should be fit to the building heights in Planet Zoo ( 4m per Segment). Wit this variant it should be possible to have a Vivarium with a size of 3x3x12m. I think this should be big enough. Maybe that is also an idea for aquariums. Generally it would be great to get butterflies, insects and maybe birds also with the Special effects variant. I think butterflies are part of the planet coaster special effects.
