Minecraft, what to build?

Does anyone have any ideas what you could build in creative on the theme of purple and black (these colors should stand out)?
I have 2 days and no life, so halfway large projects are also feasible.

A nidoran

A homemade biome. Looks cool for sure with the colors.

A spaceship, possibly. In the direction of Starwars or UFO

I just love the way you say you have no life XD

What level of difficulty should it be?

Easy:

A huge portal made of obsdian and inside purple wool with a staircase made of gray brick steps

medium

The replica of a haunted house or an attraction in an amusement park like a magic tent or an old photo development room or a zoo of bats or something with Batman, there's a lot of black - purple - dark blue

Heavy

An octopus with 8 tentacles, the nubs are purple, pink, the arms purple, black - a big project

A huge enderman, maybe.

Then show what you've built: 3

The result was asked.
I originally tried something with the underwater theme. But Minecraft looks bad underwater. At least when I do.

I then built a village with black houses around a giga tree.

I only read it, but can you see part of the result.

Can you upload a photo where or something and send it to me via PM or here? Do not currently have an MC.

Very cool!
