Assorted Fixes

Fixes toothless shark item using the placeholder fish sprite.

Fixes shark teeth being invisible
- Also slightly randomizes their position like with normal glass shards

Fixes Tobiko Sushi incorrectly being named Ikura Sushi and having an
invisible sprite

Fixes runtimes due to protein being misspelled as "protien" in 4 sushi
defines.

Fixes #1884
- This was caused by diona nymphs lacking the CANPUSH status_flag, which
is required to pass grab checks.
- Gave diona nymphs the PASSMOB pass_flag, should avoid them pushing
people everywhere, and also prevent them from being trapped by other
nymphs/people/Ian.
- CANPUSH and PASSMOB are both flags possessed by mice, so this change
effectively makes the nymph mobs closer to mice than monkeys.
