Buoy Up Puns

So mom and dad have my wife and my kid along with my sister's kid out whale watching and sent us a photo of orcas they saw. This followed...

Me: killer view!
Siss: killer view!
Me: are you thinking the same as me OR CAn you not think of anything unique and are copying me on porpoise
Me: I mean I’m having a whale of a time
Me: Did you FINish?
Me: Does your boat have a motor anD/OR SAIL?
Mom (probably dad's joke tho): You are on a roll
Me: Not sure I have many lines left actually
Me: Actually I’m beginning to waver on that statement
Me: Though it seems siss has bowed out of the conversation.
Me: Maybe she’ll come up with something after I’m done
Me: have you guys SEAn (sic) anything other than orcas?
Mom: Humpback
Me: good day for that!
Wife: Very cool!
Me: Definitely looks chilly
Wife: 20 texts... Wow
Me: Definitely an imPORTant thread to watch
Me: like how i cap-size my text to make the joke obvious?
Me: siss’ silence is fishy tho
Mom: You definitely LANDed them
Me: They just come to me and I let em sail
Me: To admit some are a bit ridockulous
Me: Which can make them tough to catch
Me: but I’ll keep tossing them out there anyway for the few that land
Me: I think we lost the point of the conversation though
Me: Let's coral it back
Me: I'm being far too shellfish by uslurping it like this
Me: But Siss did have the gull to keep repeating me
Me: Buoy that one was bad
