[disclaimer; Read: I am fiercely against Seal Clubbing, the name is meant as a joke. It's an April fools skin after all!!??]
Due to the lack of cool skins for Trundle, I would like to suggest building an Urf skin for him this year. It might improve his "played-rate" as well, since he's really not that bad.
Alright, so Urf clubber sounds a bit like Seal Clubbing, which is meant as a comical reference and not an actual practice for Trundle, so to get things out of the way, we're going to protect the living Urf that Trundle will wield as his club, with the following outfit: replace person with Urf. In other words, we will give him a stuntman helm and a stuntman star-covered outfit.
I personally picture Trundle in a Steve Irwin type of outfit, although the Manatee origin is actually not Australia. If you have a better idea, let me know, possibly with the logo of the 'save the manatee club' on his shoulders. On top of his (one) shoulder he carries a baby Manatee, which he found in the river that intersects the tournament and being the kind hearted Troll that he is, he obviously needs to bring it to safety, by winning the tournament.
A few adult Manatee notice the rescue attempts and volunteer to help Trundle beat the competition. One as his club, Urf (including stuntman suit).
Q: Rabid Bite -> Manatee Cub Bite
The Manatee cub on Trundles shoulder bites his opponent, weakening and damaging them, inspiring Trundle to fight even more ferociously!
W: Contaminate -> Ecology
The Urf-Club sprays a fountain of water in the target location, turning it into a swamp. Since Trundle knows his way best in and around the swamps, he gains attack speed, movement speed, and crowd control reduction while on it.
E: Pillar of Filth -> Manalith
Trundle calls for the aid of an adult Manatee, creating a pool of water with his Urf-Club, allowing the adult Manatee to surface from subterrean watercaverns. The Manatee blocks all passerbys and the surrounding water turns into mud, slowing all nearby enemy units.
R: Agony -> Digestive Gasses
The Manatee cub on Trundles shoulder turns around, releasing a burst of the gas it contains (to digest plants), polluting and weakening the target. Trundle is adversely affected by the gas and gains health and a percentage of armor and magic resistance, equal to the amount the target loses.
Since I can't draw any pictures for you, lack of a scanner and probably a lack of artistic skills, you'll have to deal with the image that I presented you in words. I made this for fun, because I think Trundle needs better skins and because I think he's underplayed. I will buy him after this free week.

(And yes, I'm the one that originally joked about Urf Clubber Trundle).
