Are these sentences acceptable:
1-He makes too much wave when he swims.
2-He makes too much bubble when he swims.
'Wave' and 'bubble' are both count nouns and so 'too many waves' and 'too many bubbles' would seem more grammatical here. But could one use those nouns as non-count nouns? Maybe one is thinking of the overall effect and not the number of waves/bubbles. One doesn't know if the waves are bigger or more numerous or both, one just knows that he makes the water too wavy when he swims.
Your sentences are not acceptable.
'He splashes too much when he swims.'
