It depends on the website you download it from, some might be unsafe that give you viruses or even possibly scamming you but some are safe but i recommend you buying it on Steam for legal and safe reasons
Terraria the Game can't be obtained for free since it is a game through Steam.
Talking about Animal Life (Which this was posted in), You probably can't get a Terrarium for free either.
It can be bought through Steam or downloading unofficial (illegal?) Terraria on websites, I recommend buying it through steam for your safety
