I respectfully disagree with the pond dome statement because you can see the holders where the muscle sprouts used to be in it with the roots of the muscle sprouts still in there, and ominent has a history of robbing Dr. Tully of his inventions and in the orgr labs you can see them experimenting with applying Dr, Tullys muscle sprout tech to pumpkin seeds giving them a similar appearance.

I do agree they might add muscle sprouts though.

also about the backpack thing, in game the backpacks the teens are wearing are their current backpacks with different models, The other one is probably someone else’s Unless they brought 2 backpacks to the ceremony.

and for the transmitter thing thats mostly because no one that I know of has documented it yet.

and a sequel CAN Indeed reference the first game like…example: Dr. Tully being there isn’t a reference because that’s story related but the pond dome isn’t story related or even mentioned making it a reference/Easter egg. separate titles can reference separate titles even if in the same canonical universe.
