Multiple weather Manipulation feats

2nd one might qualify as Dream Manipulation, since, although altering the contents of one's own dream isn't anything supernatural, the snow did come from his dream.
I wonder if it qualifies as Creation.
Fear Manipulation via his claws which works on living creatures as well as inanimate objects

First one might be Odie being timid, "more bark than bite", but Garfield scaring Inanimate Objects puts slight doubt on that skepticism.
The third may (also) qualify as Light or Weather Manipulation. Unsure.
Garfield loves to sleep, so it's dubious that he actually successfully hypnotized himself rather than just made a showy joke of pretending to hypnotize himself to have an excuse to fall asleep suddenly.
We see that Garfield at least mentally weakened Jon, so that's good.
The 3rd scan has Garfield claiming Odie clucking like a chicken is because Odie is just stupid. It may be worth considering the possibility that Odie really WAS dumb enough to start acting like a chicken because being told he was convinced him; Odie is often comedically, exceptionally dumb. Though there is the possibility that Garfield was just lying to Jon to either avoid getting in trouble for hypnotizing Odie, or lying because he doesn't respect Jon & for comedy.
So I'd say:
1. Dubious, feels more like Garfield just making an "I fall asleep easily" joke. Leaning more disagreeing.
2. Valid, but we only see that Garfield mentally weakened Jon, presumably to the idea of ordering pizza again.
3. Dubious, could just be Odie being comedically stupid, assuming Garfield isn't lying to Jon about Odie being dumb rather than hypnotized.
He at least has Limited Mind Manipulation, but his Hypnotic capabilities seem more debatable, IMHO.
Some how survives being
blown up
Dubious that he survived, but the thought bubble at least implies survival in the second.
Frustratingly, negative continuity often means changes to status quo from 1 strip don't carry over to the next, meaning Garfield being alive after the 1st of those scans where he exploded seems like a product of negative continuity.
Sorry for any bother; I assure you, your great efforts are much appreciated, by me at least! Looking forward to how this goes!
