Just Build! Grapple, Flying Cloud and Flying Carpet
Pick one traversal fantasy for Just Build! sky work - then verify Robux prices in-game.
When coils are not enough, Just Build! offers dedicated mobility Game Passes: Grapple Hook (~299 Robux), Flying Cloud (~299 Robux), and Flying Carpet (~399 Robux). This page compares those three for surveying plots, reaching sky volumes, and covering ground in online co-op (max eight players). Approximate prices only - always confirm in Roblox before purchase. Pair this read with Coils Tier List if you are still choosing between coil and gadget lanes, Best Value for buy order, All Gamepasses for the full catalog, and the Gamepasses Hub for navigation.
Just Build! by Awesome Fun Games autosaves your world. Mobility tools change how quickly you reach a surface; they do not replace foundation skills from Guides or control mastery on Controls. There are no active promo codes that grant these passes.
What mobility means here
Mobility tools are for:
- Reaching unfinished upper floors before stairs exist
- Crossing canyons, water features, or wide courtyards
- Scouting a friend build on the other side of a busy eight-player server
- Placing sky signs, floating islands, and roof gardens after Higher Build expands the vertical canvas (see All Gamepasses)
They are not ranked as PvP weapons. Ban Hammer (~1999) is a separate novelty purchase and is not part of this mobility trio.
Head-to-head overview
| Tool | Approx. Robux | Feel | Best job |
|---|---|---|---|
| Grapple Hook | 299 | Line, pull, climb | Facades, gaps, vertical snaps |
| Flying Cloud | 299 | Floaty aerial cruise | Surveying, gentle sky placement |
| Flying Carpet | 399 | Rideable flight pad | Sustained aerial travel, showy sky routes |
Grapple and Cloud share a price band; Carpet asks more. That alone does not make Carpet best - it makes Carpet the premium option if you want that specific ride fantasy.
Grapple Hook (~299 Robux)
Grapple Hook rewards players who think in anchors and lines. You look at a ledge, a tower corner, or a distant platform and pull yourself into position. That workflow is excellent for under-construction skyscrapers, cliff homes, and any plot where stairs are still a to-do list item. Grapple also teaches you to read the structure: good attachment points become part of how you design facades.
Strengths: precise vertical access; strong on incomplete builds; great partner to Higher Build projects. Watch-outs: if you want lazy continuous flight while decorating clouds, a flying pass may feel better. Practice tip: After purchase, spend a session only grappling between temporary poles before you decorate - muscle memory matters on both PC and mobile.
Flying Cloud (~299 Robux)
Flying Cloud is the soft aerial survey tool. At the same approximate Robux as Grapple Hook, the decision is taste and task, not price maths. Cloud travel helps you hover, inspect roof lines, and place floating decor without committing to carpet higher price. Creators who design resorts or floating islands often prefer cloud calmer pacing while they nudge pieces into alignment.
Strengths: comfortable sky editing; strong for photography-style flyovers of Builds; friendly for longer sessions. Watch-outs: if you mainly need quick snaps up a sheer wall, Grapple may feel snappier. Co-op tip: One cloud scout can call out empty lots while grounded builders place streets - useful in full eight-player lobbies.
Flying Carpet (~399 Robux)
Flying Carpet sits at ~399 Robux, matching the Beach and Winter pack price band more than the 299 gadget band. Buy Carpet when you know you want sustained rideable flight as a signature movement style - not because it is one tier above Cloud on a generic power chart. Carpet shines for guided tours of a finished district, repeated aerial commuting across a mega-plot, and players who dislike grappling aiming.
Strengths: premium flight presence; great for long aerial routes; fun social traversal. Watch-outs: weaker value if you have not tested whether Cloud already solves your sky work; easy to overbuy after owning multiple coils. Value check: Read Best Value before Carpet is your first-ever Robux spend.
Recommended mobility ladder
- Confirm coils are insufficient for your tasks (Coils Tier List).
- Choose Grapple versus Cloud based on snap-climb versus float-edit.
- Live with that tool across several autosave sessions.
- Consider Flying Carpet only if you still want a different ride fantasy or longer aerial commute.
- Avoid stacking Grapple + Cloud + Carpet + every coil in one payday unless collection is explicitly your goal.
Mobility plus other passes
- Higher Build + Grapple/Cloud: classic tall-build kit.
- Theme pack + Carpet: aerial tours of beach or winter districts look intentional.
- Paint Blocks + any flyer: colour passes still matter; flight does not paint for you.
- 2x Run Speed + flight: sometimes redundant - test overlap.
- Ban Hammer: not mobility; ignore it for this ranking.
Track your intended kit with helpers under Tools and keep learning placement flow via Guides.
Safety and etiquette in co-op
Fast vertical movement can startle friends mid-place. Agree on:
- No dive-bombing through glass roofs under construction
- Call-outs before relocating shared furniture clusters
- Who owns sky rights on floating islands
Autosave reduces disconnect pain; etiquette reduces rebuild pain.

Frequently Asked Questions
Quick answers to the most common questions.
Grapple Hook or Flying Cloud - which should I buy?
Buy Grapple Hook for snap climbs and incomplete towers. Buy Flying Cloud for calmer aerial surveying and sky decoration. They share a similar approximate price (~299), so choose by feel.
Is Flying Carpet worth the extra Robux?
It can be if you want sustained rideable flight after testing cheaper options. It is not automatically better than Cloud or Grapple for every builder. Confirm the live ~399 price in-game.
Should I buy mobility tools before coils?
If your pain is basic walking or simple jumps, try a coil first. If you need true aerial or hook traversal, mobility tools are the better lane - see also the Coils Tier List.
Do these passes work in eight-player co-op?
Yes. They are personal unlocks that help you move around shared autosaved builds. Set etiquette so flight and grapples do not disrupt teammates detail work.
Are there codes for Grapple Hook or flying passes?
No stable active promo codes are available for Just Build! at research time. Purchase Game Passes with Robux through Roblox.
