Superlative form of 'blobby'; most blob-like, shapeless, or characterized by multiple blobs.
From 'blobby' plus '-est' (superlative suffix, from Old English). This creates the highest degree of the quality described by the adjective.
English uses both '-er/-est' (one syllable comparisons) and 'more/most' (longer words) systems—you'd say 'blobbier' but 'more amorphous,' showing how our grammar rules are partly about sound and partly about tradition.
