So my question is "What triggers the scene of Dieter at the park?".
I suspect the trigger is "Nancy gets ordered to buy a parrot at the park", but that begs the question of "what triggers Nancy being ordered to buy a parrot?". Here are all the things I did before getting the "Dieter in the park" scene, the last time I played the game:
- Do all the chores on the chore list (on Nancy's computer)
- Fix the plotter
- Solve Dieter's photo challenge
- Give the photos to Jean Mi
- Get the envelope from JJ
- Make tea for Minette (a chore that's not listed on the computer)
- Buy things for Minette at the park (a chore that's not listed on the computer)
- Make cookies for J.J.
- Solve Prudence Rutherford's challenge.
- Get a high score on Model Match, so you can talk to Minette.
- Solve the dodo box challenge.
- Solve the cockroach challenge.
