Later that day, Danny, Timmy, Sam, Tucker, Cosmo, and Wanda (disguised as cats) were walking in the park.
Timmy slyly smiled at Danny and asked, "So Danny, are you finally gonna admit my ghost powers are cool and let me fight ghosts with you?"
"Yeah, they are kinda cool." Danny lied with a calm smile. "But you still can't fight ghosts."
"Why not?!" Timmy asked, disappointed.
"Because there can be some disadvantages to being half-ghost." Danny explained as he casually walked up to Timmy and stood next to him.
"Like what?" Timmy demanded to know.
Without Timmy knowing, Danny lifted his foot up to Timmy's leg and made his pants intangible, causing them to fall.
"Hey, what the-" Timmy shouted when he noticed his pants on the ground and his underwear exposed.
Everyone in the park laughed at him. Sam, Tucker, Cosmo, and Wanda stared at him surprised.
"Timmy forgot to wear Wednesday's underwear." Cosmo told Wanda.
An embarrassed Timmy pulled up his pants and ran away behind a tree. Danny and his friends followed him.
"Like I said, there can be some disadvantages to having ghost powers." A satisfied Danny said, acting like he didn't do anything.
But Sam and Tucker glared at him, realizing just what he was trying to do. The former had her arms crossed as she sarcastically stated, "You would know that from experience."
Danny ignored her and continued, "But don't worry. The house is just a short walk away, and we can totally remove your powers in no time."
Timmy, not knowing what Danny was up to, just smiled and replied, "Not a chance." Then he walked away with Cosmo and Wanda. "Besides, that's why man invented belts."
"Dang it." Danny muttered, disappointed his plan didn't work.
"You're lucky he didn't catch on to your plan." Sam said in a displeased tone.
"Yeah, man." Tucker also said in the same manner. "Did you really think that was gonna get him to change his mind?"
"You're right, guys." Danny replied, narrowing his eyes. "I need to think harder."
Then Danny snapped his fingers having come up with another plan, much to Sam's annoyance.
In the Fenton Lab, Sam and Tucker watched as Danny was attaching a piece of equipment to the wall.
"Danny, shouldn't you be protecting your cousin instead of shooting your parents' weapons at him?" Sam asked.
"I am protecting him." Danny responded, "Protecting him from making the biggest mistake of his ten-year-old life."
"And how is this supposed to help him realize this?" Tucker asked suspiciously while holding a light blue balloon.
"Simple," Danny explained. "Once my dad's ghost security camera shoots seemingly painless rays at him, he'll get freaked out and he won't want his powers anymore." Danny finished and checked his watch. "Now, Jazz should be back with Timmy any minute." Then he heard footsteps coming down the stairs. "He's coming."
"Danny, Danny!" Timmy called as he came downstairs. "You're not gonna believe it, me and Jazz were at the arcade and this jock…"
"That's great, Timmy." Danny interrupted when he came up to him.
"But, you didn't even let me finish."
"Listen, I've been thinking." Danny began explaining, "Since you have ghost powers now, you should start training."
"Training?!" Timmy shouted in disbelief. "Why would I need to train?"
"Because…you wouldn't want there to be a day when you're getting beat by a ghost and saying 'I should've listened to my cousin, Danny, and practiced with my powers', you get it?"
Timmy's fairies appear in the room, and Wanda added, "He's got a point, sport. Better safe than sorry."
"Well…" Timmy gave it some thought and answered, "Okay."
"Great," Danny took the balloon from Tucker and let it go all the way to the ceiling of the lab. "Now, let's see if you can fly all the way up there to get that balloon and bring it back here."
"Ha!" Timmy scoffed. "Piece of cake!"
Timmy transformed into Timmy Terror, and all of a sudden an alarm went off. The camera Danny put on the wall flashed a light and a laser popped out of it and began firing at Timmy. He got freaked out and flew in the air, dodging the lasers.
"Wow, dangerous lasers." Cosmo said in amazement as he watched, "That definitely makes it challenging."
When Timmy got the balloon from the ceiling, he saw a laser coming at him, and he went intangible. But the laser hit him and knocked him to the ground. The balloon popped and Timmy changed back into Timmy Turner as he groaned in pain, and the lasers stopped firing once it stopped sensing Timmy's ghost energy.
"Timmy!" Danny shouted, worried that he may have actually hurt his little cousin.
Sam glared at Danny and whispered, "Danny, I thought you said it was painless."
"I said it was seemingly painless." Danny whispered back. "Well… my dad actually said that."
"Timmy, are you okay?" Wanda asked as she and the others went up to him.
Timmy managed to stand up as he answered, "Yeah, I think so."
"Timmy, did I forget to mention The Fenton Ghost Security Camera?" Danny asked. "It fires ecto-lasers at every ghost it sees. In fact, a lot of my parents' weapons do. So, the Ghost Catcher is right over there and it'll be able to take your powers away with no problem, so what'd you say?" Danny asked, helping Timmy up to his feet.
But Timmy answered, "No way! I passed the test anyway." He threw the balloon remains in the air and it landed on Danny's head. "So that means I'm awesome when it comes to dodging your parents' stuff. Well, thanks for the training, Cuz." Timmy said as he and his godparents left.
Danny threw the shreds on the ground and growled in frustration that his plan didn't work again.
"You want us to say something to him?" Tucker asked.
Danny answered, "No, I'm capable of handling my own cousin."
"Which is why you're firing your parents' stuff at him and humiliating him in public?" Sam sarcastically asked.
"Well, I didn't want to do this. But he leaves me with no other choice."
At the docks, the Box Ghost was causing terror among all the crates and boxes that were stored in a warehouse. Suddenly, a green ghost ray shot at him, knocking him into the wall. Danny phased through the wall and flew to the Box Ghost, and then he quickly whispered something in his ear. The Box Ghost smirked and laughed, and Danny landed next to Sam and Tucker.
"What did you tell him?" Sam demanded to know.
"Oh, you know, just to 'go easy' on the rookie Halfa." Danny answered while smiling mischievously. His friends didn't look pleased with him, but Danny defended himself, "I picked the least dangerous opponent.
On cue, Timmy Turner bursts through the door with determination. "I'm here! And ready to battle some ghosts!" Timmy alerted excitedly. Cosmo wiped Timmy's forehead with a washcloth and Wanda gave him a sip of water.
"You sure you can handle it?" Danny asked in fake concern. "It's pretty dangerous."
"Stand back." Timmy replied, pushing Danny aside. "I'm Going Ghost!" He shouted, transforming into Timmy Terror.
"Hey, that's my catchphrase!" Danny shouted angrily. "You can't use MY catchphrase!"
Timmy just scoffed, "Sorry dude, too bad."
Danny quickly took a deep breath and calmed down. "Now to put Plan: Scare Terror into action." He muttered to himself and flew off.
"This plan looks like it's gonna end badly." Sam told Tucker.
"You read my mind." Wanda agreed.
Danny floated behind Timmy and started signaling the Box Ghost what to do. Getting the cue, the Box Ghost smirked and hollered, "Beware! I am the Box Ghost, feel the wrath as I crush you!"
The Box Ghost made a bunch of boxes levitate and he lunges them at Timmy. He quickly went intangible, but Danny was still behind him, and he got hit instead. Timmy failed to notice this, so he just kept attacking.
"Have a taste of my Terror Kick, Box Creep!" Timmy shouted as he flew a kick at the Box Ghost and fired purple ecto-beams at him.
Danny lied on the ground and regained consciousness as he saw the Box Ghost getting beat by Timmy. "I knew I should've picked Skulker." Danny muttered to himself angrily, even though he knew Skulker probably would've killed Timmy.
The Box Ghost soon retaliated and shot a box at Timmy, hitting him dead on, but quickly recovered.
"Is that all you got?" Timmy challenged. "I can fight you with my eyes closed!"
As a matter of fact, Timmy closed his eyes and charged ghost energy in his hands. But the Box Ghost disappeared just as Danny flew over to his spot. Since he couldn't see, Timmy fired multiple ghost rays at Danny, not knowing who he was hitting.
"Ow!" Danny shouted when he got hit. "Hey, what're you- Ah!" He got hit again. "Timmy! Ah!" Danny turned around to escape, but another ghost ray hit him, ripping the bottom part of his suit and showing off his boxers.
"Sayonara Pussycat underwear?!" Sam asked in surprise.
Tucker grinned in amusement, "I have so gotta thank Timmy for this later."
Danny turned red with anger and embarrassment as he glared at Timmy. The younger ghost boy opened his eyes and saw what happened.
But Timmy just laughed in mockery, "Nice underwear, dude!"
"I've had it!" Danny shouted as he flew in front of Timmy. "I'm sick of you always getting in the way and acting like a show off with your powers!"
Timmy just glared and shouted back, "Just like you?!"
"You are NOT like me!" Danny retorted.
"YOU'VE been bossing me around all week!"
"Well, if you had just listened once in a thousand times I've told you…"
The two half-ghosts began arguing over each other again as the fairies and teens stare up at them. Wanda and Cosmo held up their wands, prepared to silence them, but Sam held up her hand to stop them. She sighed in annoyance as she took out two Fenton Thermoses and gave one to Tucker. "You get Timmy."
While Danny and Timmy were still arguing, Sam sucked Danny into her thermos and Tucker sucked Timmy into his.
Then the Box Ghost came up to Sam and Tucker. "Hey, the child promised me a 56 inch box!"
