Shiny Grubbin

Grubbin's shiny adjusts its orange mandibles and body to an almost identical shade. The grub with pincers was never going to be a shiny hunting target, and the non-existent color change confirms it. Bug larvae continue their streak of bottom-tier shinies.

How do we research these odds?

We check every game where a shiny is possible, then rank each one by the best method available in that game, so the row at the top is the fastest route overall.

Odds marked verified are cross-checked against multiple independent sources before we publish them. Where a rate is not yet confirmed we mark the row pending rather than guess a number.
