2 Tentacle Slaps and Bite (3.0 to 3.5e question)

[Mighty Halfling]

Last night's game featured a confrontation with a Mudmaw (Monster Manual 2). The Mudmaw was published under 3.0 rules, we use 3.5e.
In the book, the mudmaw's full attack is listed as 2 tentacle slaps at +11 and a bite at +6.
So, if it launches all of these attacks in one round, are the attacks +11/+11/+6 ?
The creature doesn't have a multiattack feat. Does that mean that the full attack should be +9/+9/+4 ?
Or should it actually be something more like +11 (tentacle 1)/+6 (tentacle 2) /+1 (bite).

Generally, monsters with this sort of smack/smack/chomp combo go +x/+x/+y, where y is 5 less than x. So +11/+11/+6. If it had multiattack, that would become +11/+11/+9.

RangerWickett is generally right, though I don't remember the BAB and Str bonus of the mudmaw to tell you whether it should be +11 or +9 for the slaps.

This wasn't really a 3.0 vs 3.5 question (I think), but, in case something comes up, here are the update booklets for converting 3.0 monsters to 3.5.

Yes

No that means the secondary natural weapon (the bite) is at -5 from the primary instead of -2 as it would be if it had multiattack. Primary natural weapons never suffer a penalty from using secondary ones.

Or should it actually be something more like +11 (tentacle 1)/+6 (tentacle 2) /+1 (bite).

No, that would be using something close to iterative attacks but with different weapons for each attack. Natural weapons do not follow the iterative attack rules at all. The tentacles go at the same attack bonus as they are both primary natural weapons. Natural weapons such as claws and tentacles and elemental slam attacks also don't have the same offhand penalties that fighting with manufactured weapons do.
