Builder: Mission has started.

Architect: alright,

Architect: this is harder

Architect: start with a stack of 5 purple blocks in the middle

Builder: place purple -1 1 0, place purple -1 2 0, place purple -1 3 0, place purple -1 4 0, place purple -1 5 0

Builder: Now what?

Architect: cool!

Architect: extend the top purple block to a row of 5 purple blocks

Architect: so like an upside down "L"

Builder: So they should extend to one side,

Builder: correct?

Architect: yep!

Builder: pick purple -1 5 0, place purple -1 5 0, place purple -1 5 1, place purple -1 5 2, place purple -1 5 3, place purple -1 5 4

Architect: nice!

Architect: now, put a block above and below the second block from the right

Builder: What color should those blocks be?

Architect: also purple!

Builder: place purple -1 6 4, place purple -1 4 4

Architect: 2nd block from the right,

Architect: so one more space over each

Builder: Oops,

Builder: my mistake

Builder: pick purple -1 4 4, pick purple -1 6 4, place purple -1 4 3, place purple -1 6 3

Architect: okay,

Architect: now you'll want to build the top stack up by one more block

Architect: sorry

Architect: the top block that you just built i meant

Builder: place purple -1 7 3

Builder: Ok,

Builder: so this?

Architect: yeah!

Architect: and then a block to the left of that

Builder: place purple -1 7 2

Architect: and remove the 2nd last block you just put down

Builder: pick purple -1 7 3

Architect: okay,

Architect: now do the same thing upside down on the bottom,

Architect: so it looks like an arrow head

Builder: Okay,

Builder: makes sense

Builder: pick purple -1 5 2, place purple -1 5 2, place purple -1 4 2, place purple -1 3 2, pick purple -1 4 2

Builder: Anything else?

Architect: perfect!

Architect: i think we're done!
