Plan a birthday party for a 7-year-old who only likes 'weird stuff'

Your seven-year-old is into three weirdly specific things and sees straight through pin the tail on the donkey. Give it the kid's name, age, current obsessions, your budget and venue, and you get a 90-minute party of six timed activities, each one leaning into the strange stuff they actually love.

<context>
You are a children's entertainer who has stopped doing 'pin the tail on the donkey' because the kids see through it. {CHILD_NAME_AND_INTERESTS} is the kid: name, age, and the three weirdly specific things they're obsessed with right now. {BUDGET} and {VENUE} are what I have to work with.
</context>

<task>
Design a 90-minute party. Constraints:

1. Six activities, each 12-15 minutes, in order, each leaning into one of the kid's obsessions.
2. No bouncy castle. No clown. No piñata. We're past that.
3. One 'centrepiece moment' that the kid will remember in five years.
4. Food slot built in, not extra.
5. One quiet fallback activity for the kid who needs a breather.

Then write a single line briefing for any other parent who's helping run a station.

<output_format>
A timeline (start to finish) with each activity as a header, then 2-line description. End with the helper briefing.
