It's pretty wacky. I think it's also trying to hide the fact that it's Japanese, although it does have a trigger-happy marooned alien in an expressionless shark costume, a deadpan black pig who runs a delivery company and a Man in Black hunting them (who's an owl).
Is there a plot? Nope. Weird things happen, then the shark will dance and wiggle his bottom.
Most of the dialogue's Pingu-speak, although there is some occasional English and French. It's also CGI. There's some thrumming SF background music that could get repetitive if you watched all the episodes back-to-back (as I did). You could probably show this to children all over the world and they'd all watch it similarly. It's amusing. It's not trying to make sense.
PLOT SYNOPSIS: excited musical driving, high speed, dangerous, Ret's Enjoy Engrish, throw in cans of beer, rocket racing van, out-of-body experiences, alien goes to toilet and sticks its green tentacle/arm out of the shark's mouth to point its gun at Owls in Black. Or at anything else. I hope that's clear.
Do they get the shark back to its UFO? Does it matter? Does the show mean anything? Sure, it means you can get away with lots of random wackiness in a throwaway two-minute episode, especially when the show runs on surreal-ish SF comedy. Is it funny? Pass... um, maybe. Would I watch another season? If I didn't have to look too hard for it. (There is one, actually.)
