0:09:55 > 0:09:59- Well, uh, uh... I painted a - white sea cucumber with octopus ink.
0:10:00 > 0:10:02- What?
0:10:04 > 0:10:06- He deceived me.
0:10:06 > 0:10:11- I know you like being the best - but submarines don't cut corners.
0:10:12 > 0:10:13- Nor do they cheat.

0:10:24 > 0:10:27- I'm sorry you have to clean - the cages.
0:10:28 > 0:10:29- Go away, Sid.
0:10:29 > 0:10:33- Don't be angry. I'll help you.
0:10:33 > 0:10:36- No. I don't want your help.
0:10:36 > 0:10:41- If I help you, you'll finish - the job quickly and we can...
0:10:41 > 0:10:43- Oh, eurgh!
0:10:43 > 0:10:47- I think both of us - have learnt a lesson today.
0:10:47 > 0:10:50- From now on, I'll do my own work.
0:10:50 > 0:10:53- I'll keep away from sea cucumbers!
0:11:26 > 0:11:26- .
