>>715591576Spider Guardian is a Morph Ball miniboss. You must use Boost Ball and Bombs to stun the boss and trigger switches to detour the boss into damaging barriers. The final segment requires you to repeat this a few more times in the same section. It is perhaps the most-involved boss in this category.
It requires more patience on the GCN version, as the Wii re-release inherently has the Spring Ball ability when you have Bombs; it is much faster and responsive despite the waggle. The Wii version also nerfs Boost Guardian directly, and if Retro remasters Echoes, it will likely inherit these changes.
