What purple spider-like pet is this in Oldschool Runescape?

I was bankstanding and saw a guy standing there with this awesome looking pet I have never seen before.

I looked around on the wiki and it doesnt look like any of the boss or skilling pets. What pet is this and how can I get one?

That is an Olmlet pet metamorphosised to the Vasa Minirio variant. It can be obtained by first getting an Olmlet in Chambers of Xeric, and then obtaining metamorphic dust by completing Chambers of Xeric Challenge Mode within the target time as a 1/400 drop.
