The Forbidden Temple round is completely random, it's not a glitch. You could get 5 animals, a lot, or none. I have never had a problem with it except when I got no animals of course, but once you compared it to fireworks losing their fireworks and clams breaking, I suddenly felt like we've been cheated in Jungle Cruise.
Fireworks players have no other difficulties that impair their scores other than their skill. Clams has no difficulties other than more players which is easily remedied by creating a new room. Jungle Cruise if you're unlucky you could go from finally breaking that 40k mark for a key, to falling short once again based purely on bad luck. If the original was like that I can understand why they'd want to keep it how it is, but if there was anyway Amy and Staff would reconsider I'm sure that would make a lot of us happy
